How fast can buildings be built these days?

The idea of a nuclear chain reaction arose around 1930-40, the first reacton (Chicago Pile), a very barebones design, in 1942. Later, in 1956, a small (by today’s standards) plant at Calder Hall and a more experimental plant at Obninsk some years earlier were the first nuclear fission plants providing power for civilian purposes.

Physics has been proclaimed to be dead a few times. Is this time for real?

Nat Friedman asked twitter for technology (or achievements enabled by future tech, or broadly “cool stuff”) people are excited about, and quite a few replied. Here’s a compiled list by theme with some comments. Some of these may not make sense as stated, if so have a look at the thread.
In bold are things that I thought of not included in the original list.
The ones that I see as most interesting are the ones related to medicine. One, because a better understanding of medicine will mot likely reduce costs, and healthcare expenditures are quite big in most countries. Second, because when aging is cured, some people will chose to continue working forever, which may decrease pension expenditures somewhat. And third, because illness and unchosen mortality are bad.
Collection of papers and articles that I’ve spotted since my previous links post that seem interesting.
[Epistemic status: Possible. I’m introducing epistemic tags in the blog, stealing them from Gwern. This post is more of an speculation that rings sort of true, but I’m not too confident about it. Until know, when I’ve written something here, I’ve intended it to be a final statement, given the total sum of knowledge available to me at the time, but I’m experimenting with making posts that say things I think, but that I am less confident about. As a result, what follows below may be no more than a glorified rambling.]
What is public and private these days?
