A children's book written in 1954 inspired by Wiener's Cybernetics that explains some common day analog systems:

Analog computation originally meant the construction of a simulation of another system by means of a mechanical or electrical system that represented the same dynamics as the physical system. That is an analog of what's being simulated.
Nobert Wiener generalized this idea in Cybernetics to describe control systems that through negative feedback promoted stability. https://t.co/15doR3gxUk
W.Ross Ashby argued that negative feedback was insufficient for maintaining the stability (homeostasis) of complex system. Ashby proposed the Law of Requisite Variety. https://t.co/T4KbmZNLpL
These machines that 'seem to think' are examples of what was known as analog computation. Cybernetics, control theory, biology are examples of analog computation. But what does this mean other than being the opposite of discrete/digital computation?
Computation in an abstract sense is the interplay of intention and mechanism. That intention may be homeostasis, perception or action. Analog systems use mechanisms of this world to implement the mechanisms required to fulfill intentions.
This is in contrast with discrete digital systems that operate in a virtual reality distinct from their underlying implementation. The only virtual analog systems we have are the kinds that are simulated using digital systems.
The other distinction of an analog system is that perception and action can be continuous. Said differently, continuity has meaning in an analog system. In fact, I would argue that the basis of meaning is dependent on continuity.
A digital system (language as an example) has meaning as a consequence of standardization. That is, agreed-upon norms of interpretation. Meaning in digital systems is an emergent feature of collective behavior.
Collectives are composed of individuals that create meaning through the observation of continuity in this world. What Peirce identifies as icons and indexes are signs that express continuity. That of a similarity relationship or a causal relationship.
Prior to the emergence of brains, organisms interacted with this world through hardwired mechanisms. This mirrors how analog systems interact with the world through the physical mechanisms of this world.
Brains however introduce an entirely new behavioral repertoire that is divorce from actual mechanics. Brains predict their analog realities through mechanisms that are yet to be understood.
Brains are able to virtualize analog realities in a manner very different from how digital computers virtualize analog reality. (Left to reader why this is obvious)
We have two options of how to brains could be implemented. Brains could be either (1) analog machines that virtualize analog realities or (2) digital machines that virtualize analog realities. The spiking behavior empirical observed appears to indicate that it is of the 2nd kind.
However, Deep Learning appears to allude to an analog machine virtualizing an analog reality. This is difficult to understand, but that is what Deep Learning appears to show.
However, there is a 3rd option. That is, the brain is both digital and analog. Biology employs the strategy of code duality across multiple scales. My expectation is that this is also the brain's strategy.

The interview with CNBC of @chamath is a much watch because there is so much insight hidden underneath.

There are many things that caught my attention. The one thing was the abstraction that hedge fund strategies are all 'momentum' plays. What it seems to imply is that the marshaling of resources at an opportune time drives the future behavior of a stock.

From basic physics, we know that momentum is mass times velocity. So any 'momentum' tactic employs the variation of mass, velocity or both. Wrt stocks, mass is money and velocity is speed of trade.

We cannot argue that there are benefits of scale associated with having more money. Also, high-frequency trading has shown the value of high-speed trading. So in an abstract sense, market manipulation can involve a kind of momentum play.

The objective of stock trading is to buy a financial instrument at a low price and sell it at a higher price. The purpose of a momentum play is to front-run the decision process of other traders such that one acquires the assets before a decision is made.

Does artificial anthropocentric intelligence lead to superintelligence?

When I use the term Artificial General Intelligence, my meaning of 'General' comes from the psychology definition of the G-factor that is tested in general intelligence tests.

It is an anthropocentric measure. The question that hasn't been explored in depth is whether a "human-complete" synthetic intelligence leads to a superintelligence. The prevailing assumption is that this expected.

I am going to argue that this assumption may not be true.

The assumption that goes into AGI automatically exploding into a superintelligence is driven by the bias that human intelligence is perceived at the pinnacle of all intelligence.

Damasio in his book 'The Strange Order of Things' argues that the core of condition lies in homeostasis. I agree with this generalization. But let me work out in a tweet storm how consciousness relates to homeostasis.

Human consciousness is related to awareness of surprising or threatening observations. It's an error-correcting mechanism that lends attention to discrepancies of our expectations of the world.

The mind is composed of many layers of cognition. Also, its massive parallelism implies reducing the conditional checks required for error correction.

To do this, consciousness is engaged only in a time-sliced manner in a periodic manner. The majority of time spent is in unconscious activity with only periodic activation of the conscious error-correcting process.

The system 1 unconscious intuitive mechanism minimizes the effort of performing error correction. It is automated and driven by habit. It is like a river flowing without obstructions.

Programming in abstractions is very different from a system that is capable of its own 'abstracting'. But what does abstracting mean? We only know of its inputs and outputs, but we fail to describe its inner workings.

I like this short video about living in space. This is because it makes you realize the gaps in your knowledge when you turn off something (i.e. gravity) that you have always assumed to be present.


Perhaps we can understand 'abstracting' better if we turn of many assumptions that we unconsciously carry around. Perhaps we need to get rid of the excess baggage that is confusing our thinking about abstraction.

Turning off gravity and living in space is a perfect analogy. We somehow have to turn off a cognitive process to understand the meaning of abstraction.

The first step to divorce ourselves from our habitual cognitive processes is to realize the pervasiveness of 'noun-thinking' .

In physics, energy is that which is causally invariant or symmetric with respect to time. Said differently, energy is never created or destroyed, it is conserved in the universe.

Now there is a question about information. Is information causally invariant? Does information remain the same with respect to time? To understand this, let's first understand what energy is, then attempt to understand what information is.

The strange thing about energy is that it is this universal currency that seems to be interchangeable between the different forces in nature (i.e. electromagnetic, strong, weak and gravity). It is that thing that makes change possible.

Now let's assume that the universe is computational in nature. That is, anything we see in nature is a consequence of computation. That is, there is computation underneath the physics that is driving the universe to change.

What does it mean then that information is conserved in this computational universe? Also, how is energy conservation related to information conservation?

Finished Psychology of Money by @morganhousel

Just phenomenal. Here’s some favorite highlights

It’s a soft skill, where how you behave is more important than what you know.

To grasp why people bury themselves in debt you don’t need to study interest rates; you need to study the history of greed, insecurity, and optimism.

To get why investors sell out at the bottom of a bear market you don’t need to study the math of expected future returns; you need to think about the agony of looking at your family and wondering if your investments are imperiling their future.

I love Voltaire’s observation that “History never repeats itself; man always does.” It applies so well to how we behave with money.

Your personal experiences with money make up maybe 0.00000001% of what’s happened in the world, but maybe 80% of how you think the world works.

The challenge for us is that no amount of studying or open-mindedness can genuinely recreate the power of fear and uncertainty.

Otherness and Power: Michael Jackson and His Media Critics is a rather short book by Susan Woodword but it does a lot to expose "progressive" hypocrisy in the media and academia.

It analyzes three works:
- A 1985 book by Dave Marsh called "Trapped: Michael Jackson and the Crossover Dream"
- Maureen Orth's MJ articles in Vanity Fair
- And a 2009 book entitled The Resistible Demise of Michael Jackson, edited by British music critic Mark Fisher

I went back to the latter part today because I heard Fisher's name again in a completely different context (he was also a philosopher) and it kind of ringed a bell, so I checked back if he was really the dude who wrote some horrible book about MJ?

Well, he didn't write it alone (he personally wrote only one chapter), but he edited it. As per Woodward the book is short on actual facts and research on MJ's life, but high on opinionated and dehumanizing hatred based on tabloid information and their perception of him.

What Woodward does is making lists of the adjectives the books' authors use of Jackson. That in itself shows the out of control, irrational hatred.

You know the old adage, “It’ll probably get worse before it gets better”? Oh, and this one: “It’s always darkest before the dawn” and, meanwhile, that coal-black night seems to go on for eons? Exodus 5 in my morning reading. If you didn’t know God was faithful, you might think

He liked getting you into trouble. Moses has returned to Egypt. Aaron’s reintroduced the former prince to the Israelite elders. Told them God has seen their misery. Moses performed a few signs. They’re bought in and bowed low in worship by the end of Exodus 4. Then Moses & Aaron

go to Pharaoh with the Lord’s message: “Let my people go.”
No. “Please.” Nope. Can’t lose my labor force. So Pharaoh commands overseers to drastically increase the Israelites’ workload without changing their daily quota. When they can’t fill it, the Israelite foremen are beaten.

The Israelite foremen go to Pharaoh & cry out for help. He says, “You are nothing but slackers! Now get to work!” So they do what you know they are going to do and do not blame them for doing and know you would do it, too. They go to Moses and Aaron. “What have you done to us?!?”

Moses then goes to the Lord. “What have you done to them??And why did you ever send me?? Nothing but trouble has happened since we did what you said. “AND,” Moses cries, “You haven’t rescued your people at all!”

It’ll be that way sometimes. It’ll get worse before it gets better.

Ameda Temple
Ernakulam, Kerala 🚩
#keralatemples

Ameda Ksetram is located in the banks of Vembanad Lake. Temple is very unique and Powerful Sarpa Kavu.
Parashurama did Prathishta here. Vilakku which was lighted by Parasurama is still seen inside the temple.


The oil from this lamp is given to bhakthas for recovering from illness.

Sthala puranam says that, Once, when Parashurama was travelling through Kerala, he reached this place. As it was evening, he stepped into the Lake for Sandhya Vandanam
At that Sapthamathrukkal 👇


(Brahmini, maheshwari, kowmari, vaishnavi, varahi, indirani and chamundi) were travelling there on a tortoise through the water. The tortoise was unable to move, because the Water had made its way for Parashurama. The place where the tortoise became Still came to be known as 👇


Aama Ni Nidayam' ( Aama means tortoise) and later become ‘Ameda’. Parashurama came to know about the journey of Sapthamathrukkal. Thus, he did Prathishta for the Sapthamathrukkal here.
7 forms of Aadi Parashakthi are Sapthamathrukkal. Veerabhadra and Ganesha have Sannidhi here.


The main Garbhagriham in the temple is the Sapthamathrukkal. There are Sannidhi to Nagas, Nagayakshi and Vishnu too. Sarparadhana or snake worship is done here. Naga Panchami is famous here. Those who have Naga Dosham come here and get relieved of their Doshas.

Ancient Egypt was the most advanced civilization in the ancient world. Why was Egypt so special?

There are so many firsts in Egypt that we all know about, and that makes Egypt unique. For example, the Sumerians did not build the pyramids of Egypt.

There's been a lot of talk about the missionary killed by the natives of North Sentinel Island. They're probably so aggressive because of this weirdo, Maurice Vidal Portman. So here's a big thread about this creep and some facts from my decade-long obsession with the island.


The Sentinelese are often described as “uncontacted,” but this not strictly true. They had a very significant contact in 1880 with Commander Portman.

Portman, the black sheep third son of some minor noble, was assigned by the English Royal Navy to administer and pacify the Andaman Islands, a job he pursued from 1880-1900 with the full measure of his own perversity.


Portman was erotically obsessed with the Andamanese, and he indulged his passion for photography by kidnapping members of various tribes and posing them in mock-Greek homoerotic compositions.


During his 20 years in a sexualized heart of darkness, Portman measured and cataloged every inch of his prisoner’s bodies, with an obsessive focus on genitals.
