To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known. https://t.co/BKLqhrBeEL

* Language is low bandwidth: less than 12 bytes/second. A person can read 270 words/minutes, or 4.5 words/second, which is 12 bytes/s (assuming 2 bytes per token and 0.75 words per token). A modern LLM is typically trained with 1x10^13 two-byte tokens, which is 2x10^13 bytes. This would take about 100,000 years for a person to read (at 12 hours a day).

* Vision is much higher bandwidth: about 20MB/s. Each of the two optical nerves has 1 million nerve fibers, each carrying about 10 bytes per second. A 4 year-old child has been awake a total 16,000 hours, which translates into 1x10^15 bytes.

In other words:
- The data bandwidth of visual perception is roughly 16 million times higher than the data bandwidth of written (or spoken) language.
- In a mere 4 years, a child has seen 50 times more data than the biggest LLMs trained on all the text publicly available on the internet.

This tells us three things:
1. Yes, text is redundant, and visual signals in the optical nerves are even more redundant (despite being 100x compressed versions of the photoreceptor outputs in the retina). But redundancy in data is *precisely* what we need for Self-Supervised Learning to capture the structure of the data. The more redundancy, the better for SSL.
2. Most of human knowledge (and almost all of animal knowledge) comes from our sensory experience of the physical world. Language is the icing on the cake. We need the cake to support the icing.
3. There is *absolutely no way in hell* we will ever reach human-level AI without getting machines to learn from high-bandwidth sensory inputs, such as vision.

Yes, humans can get smart without vision, even pretty smart without vision and audition. But not without touch. Touch is pretty high bandwidth, too.

*The Accident*

My 11-year-old daughter and I had a near death experience on the Mumbai- Pune express highway on November 19 (Sunday).

This is our account and I hope that @nitin_gadkari @CMOMaharashtra @Devendra_Office @TransportofMAHA and @Uber @Uber_Support shall take the necessary action to ensure that no one else has to undergo this ordeal.

#roadaccidents #Mumbai #Pune #MumbaiPuneExpressway #roadsafety

On Saturday, I took the train for Pune to pick-up my daughter. I am a great fan of the @RailMinIndia as the trains between Mumbai-Pune are by and large punctual, safe, and help avoid traffic jams. But our train tickets were wait-listed and hence we had to book an Uber cab for Mumbai.

The driver was very polite and rated at 4.93. When my daughter showed some signs of motion sickness, he voluntarily stopped the cab before a chemist for me to buy some medicines.

Enroute, he began speaking on the phone. I find this disconcerting and unsafe but did not want an argument or escalation in the presence of my daughter.

Soon after we took the Expressway, the driver began yawning. He also drove rashly at times, cut lanes, and almost brushed against a truck. I asked him if he was sleepy or drowsy--I had been able to gather from his conversations on the phone and our own small talk that he had come to Pune after picking up a customer early in the morning. But he said he was ok--the yawning was being induced by the AC! I asked him to stop the car and splash some water on his face, which he did.

I engaged him in small talk to keep him awake. Soon after we descended the ghat and reached Khopoli, there was a truck bang in the middle of the carriageway. Even as I yelled at him to watch out, our car smashed into the rear end of the truck. The airbag activated and slammed against my chest. I was dazed and in immense pain from the impact but instinctively looked at the rear seat to check on my daughter. She was rattled but kept calm. Thankfully, the driver was OK. We were incredibly lucky to have not been tail-ended by another speeding car on the busy highway.

A techie lost ₹10 Lakhs of borrowed capital in stock market. 3 key things you need to know before getting started 👇

<<A long post but I’m sure those reading this will avoid a lot of blunders in future>>

[1] Share market can't be your retiring early plan

If you are fine with making slowly with returns of 10% to 15% p.a., and seeing your investments go down by 25% every year and 50-60% once in a decade, then only enter stock markets.

But if you think you can 10x your capital within a year, please know that the probability of this happening is less than you breaking the record of Virat Kohli's 50 ODI centuries.

[2] Those making money won't sell you courses

Rakesh Jhunjhunwala turned ₹5,000 to ₹35,000 Crores in ~35 years of his career at a CAGR of 64%. Did he make courses before dying?

I know a person who has sold stock market courses worth crores but doesn't know the difference between QoQ and YoY.

Those who know jackshit about trading will invest their energy in making money and not courses (with an exception of a very few).

[3] Futures & Options is a zero-sum game and 89% make losses

This is not my observation but SEBI's data. And the 11% who made money made just ₹12,000 per month on an average.

If I talk about observation then my father (a CA) is a part of top CFO and CEO circles in Delhi. Not one of these top CFOs or CEOs has made anything from F&O.

When one person's loss is someone else's gain, that game / business is called a "zero sum" activity where no one but brokers make money. Another example is poker / gambling.

Isn't it better to invest that amount in upskilling yourself and increasing your active income?

And my dear friends, this is the only way to get rich faster in life. Be as passionate as you are about F&O for upskilling for just 1 year in life. And this will be the best investment you can make.

It is saddening to see a young guy jumping off who took debt to play in stock market.

I know posts like these won't go viral because I didn't give you "10 multibaggers of 2024" or "5 call options to get rich by 3:30PM today" like calls.

But this boring truth is the reality of life and I want you to read this once in a while so that you don't end up taking steps like these. At one point, I lost ₹25 Lakhs to a stupid get rich quick scheme like this.

There's no other way to get rich in life but this:

Hard Work --> Increasing Active Income --> Making sensible asset allocation decisions.

Do consult a SEBI Registered Investment Advisor before taking any call. They'll help you a lot for a very small fee. My words are for your education only :)

Follow me for more such boring personal finance & investing gyaan!

[Aman Goel @amangoeliitb]

One good thing I did when I joined IITB was to make a commitment myself that I won't ever ask for money from my parents from this point onwards.

In my first year, I did a lot of side work to earn. Solving JEE question papers for Plancess, Creating content for Toppr, Freelance Website development, Running and Monetizing my own blog, Writing JEE preparation articles for Wiley Publishers and a lot more.

Later in the 4th year, I converted all of this freelancing activity into a small scale Content Business with @harshitaiitk where we were doing ~Rs. 2.5 lakhs of monthly profit, managing a team of ~20 freelancers. All of this when we were still in college!

This whole learning experience of earning money in college really helped us build the foundation for entrepreneurship. We learned the basics of Sales, Customer handling, Escalations, Hiring and SOP building.

More people should try these things - not just for money, but also for the lifelong learning experience. Really helps in learning the basics of Entrepreneurship in college itself.

Five of us were waiting at a doctor's clinic today. Four were looking in their mobiles and I was reading a book. I felt like an odd man out.

One of them looked at me as if I don't belong to this era.

[Physics In History @PhysInHistory]

A 1597 letter from Galileo Galilei to Johannes Kepler ✍️

4th August, 1597
...Like you, I accepted the Copernicun position several years ago and discovered from thence the causes of many natural effects which are doubtless inexplicable by the current theories. I have written up many of my reasons and refutations on the subject, but I have not dared until now to bring them into the open, being warned by the fortunes of Copernicus himself, our master, who procured immortal fame among a few but stepped down among the great crowd (for the foolish are numerous), only to be derided and dishonored. I would dare publish my thoughts if there were many like you; but, since there are not, I shall forebear..

To which Kepler replies the same year ✍️

....I could only have wished that you, who have so profound an insight, would choose another way. You advise us, by your personal example, and in discreetly veiled fashion, to retreat before the general ignorance and not to expose ourselves or heedlessly to oppose the violent attacks of the mob of scholars (and in this you follow Plato and Pythagoras, our true perceptors).

But after a tremendous task has been begun in our time, first by Copernicus and then by many very learned mathematicians, and when the assertion that the Earth moves can no longer be considered something new, would it not be much better to pull the wagon to its goal by our joint efforts, now that we have got it under way, and gradually, with powerful voices, to shout down the common herd, which really does not weigh the arguments very carefully? Thus perhaps by cleverness we may bring it to a knowledge of the truth. With your arguments you would at the same time help your comrades who endure so many unjust judgments, for they would obtain either comfort from your agreement or protection from your influential position.

It is not only your Italians who cannot believe that they move if they do not feel it, but we in Germany also do not by any means endear ourselves with this idea. Yet there are ways by which we protect ourselves against these difficulties....

Be of good cheer, Galileo, and come out publicly. If I judge correctly, there are only a few of the distinguished mathematicians of Europe who would part company with us, so great is the power of truth. If Italy seems a less favorable place for your publication, and if you look for difficulties there, perhaps Germany will allow us this freedom.
