Extracts from a Diary

The nuclear age left radioactive traces in all modern steel. The LLM age is doing the same to digital content. Some analogies and lessons from that. Radioactive Signature on Steel From around 1945 onwards, in specialised niches and applications, there came up a need for specialised steel — steel that was made from before 1945. You see, after the nuclear tests and detonations, there exists a certain level of diffused background radiation in atmosphere. While these detonations happened in US and Japan, initially, followed by USSR and elsewhere, the radiation spread quickly and to somewhat uniform levels, throughout the world. The typical steel-making process uses atmospheric oxygen. And this background radiation in atmosphere leaks into the steel-making process. All steel made after 1945 has a certain level of radioactive traces (or its radioactive signature) slightly and measurably higher than for steel made before that cut-off. There are a set of highly sensitive, niche applications, w...

Last week of August, I was fortunate to have travelled to Vietnam. I say fortunate because I loved every bit of it, and hope to be able to travel there again. We visited Ho Chi Minh City (also called Saigon or HCMC), Da Nang, and Hanoi — the three major cities across South, Central, and North Vietnam respectively. Each of those had a different flavour across the many dimensions — food, culture, traffic, road infrastructure, markets, coffee, among other things. Our trip was for about 8 days, and we definitely felt that was too short to fully soak in the things the country had on offer. But, it’s better to leave with an incomplete appetite and a desire to return, than otherwise. It was an excellent trip in absolute sense and in terms of value for money. History While Vietnam has had a continuous history of about 3000 years, in the modern era, it’s been a theatre of the different world powers. Under French colonial rule until World War II, control shifted to Japan after France fell to Naz...

Examining claimed market failures, government intervention, and the regulatory alternatives that were ignored It’s not often that you get one clean-and-cut story that at the same time showcases: Government’s natural tendency to consolidate more power and reduce citizens’ freedoms, their swift movement in doing so, in a growing industry that has a large number of business-to-consumer users, and the overwhelming discourse, even among the otherwise basic economics educated individuals, is actually cheering them on in this move. But, that’s what happened. The government (of India) recently came out with a bill that effectively banned ‘real money gaming’ (RMG). It banned apps that allowed or facilitated gambling or fantasy leagues, where people bet actual money. It’s a 10 page bill and can be read here ( link ) if one is interested. It passed on Friday, 22nd August 2025 after the President Droupadi Murmu signed on it. In about 4 days from the time it re...

Nihilism: The Case for No Inherent Meaning to Life Two anchoring sets of facts: We’re on a pale blue dot called Earth that orbits a modest-sized star, barely noticeable in an otherwise average galaxy containing 10 11 other stars. This galaxy is part of a supercluster containing 100,000 other galaxies. There are probably about 10 million other superclusters in the observable universe. The universe began about 13.8 billion years ago. Earth formed 4.5 billion years ago. Modern Humans appeared around 300,000 years ago (~0.0067% of Earth’s current age), and all of written history — and any named human — are from less than 10,000 years ago (~0.00022% of Earth’s current age). These timelines and scales are so huge that they are humanly incomprehensible. People realise this and move in either direction — incredible religious awe as well as those around rejecting it. You could be like the young protagonist of Annie Hall (1977 movie), who on hearing that the universe is expanding ( 45 seconds ...
