The brain undergoes a great “rewiring” after age 40

Have to question the objectivity of the research. Not that overall there is cognitive decline, this is undeniable, but you could also expect some type of advantage in the wiring being more integrated holistically and there being less rewiring. The tone of the article makes it seem like they did not consider any potential advantage.

I'm 44. I definitely see that my worldviews are much better formed than I was when I was 21 or something. And less interested in learning a new programming language every two years.

But I have concrete and integrated ideas and implementation plans for improving things now.

And I can certainly integrate new information as it comes in. For example I think that C++ and JavaScript are obsolescent, and things like Rust and TypeScript will replace them.

Also I wonder now with digital signatures being built in to browsers (Webauthn) and ipv6 deployment increasing, could some type of web-native cryptocurrency take over within a few years?
