On building

It's time to build, writes Marc Andreessen. The piece is framed in the context of the Covid pandemic. The first part of the essay is about preparation for pandemics, Part of the problem is clearly foresight, a failure of imagination. But the other part of the problem is what we didn’t do in advance, and what we’re failing to do now. And that is a failure of action, and specifically our widespread inability to build. There is one more that can be added, besides failing to plan or build: failing to maintain…

Progress in semiconductors, or Moore's law is not dead yet

Moore's law is relentless - Jim Keller In its original formulation, Moore's law1 was about cramming more transistors in ever decreasing surfaces; by that metric Moore's law continues unabated. However that's not the most interesting thing. As much of a feat of engineering it is, most people are interested in the end-product of the semiconductor world: performance. Before moving onto that, here are some charts that show progress in the original Moore's law sense (ht Sam Zeloof for the data). Of note here i…

Comments on 'Fully Grown'

You might remember a post I wrote in 2016, No Great Technological Stagnation where I argued various things that are worth repeating and valid today: Technology is not the same as productivity growth, and there is no great stagnation in technology; rather there are localized slowdowns, accelerations, and stagnations1, and of course TFP is more than technology. Also last year I wrote on whether WWII was good for growth, and I linked to some evidence that the rate of growth of population could be behind a stag…

The Longevity FAQ: Making of

So I just published the Longevity FAQ. This represents my first blogging foray into molecular biology. So it happens, I hadn't really studied biology since high school, so here's how -and why- I went from zero to writing a FAQ on a complex topic. Why write about it, in the first place? An original motivation is that I've said a bunch of times that I see more progress in the future coming from the life sciences rather than physics, yet my knowledge in biology was very, very lacking, not having ever seriously…
