I'm not coonvinced by the conclusion. The contacts example doesn't show friction leads to growth, it shows absence of friction leads to degrowth. The other way around isn't necessarily true.

I'd argue it doesn't show growth or shrinking. What capacity does remembering strings of numbers "grow"? There's no clear connection to remembering other things, or math skills, or anything but how many numbers you remember.

The author says they still remember these numbers. Maybe they remember fewer and this is shrinking? Seems like a poor example at any rate.

Necessary but not sufficient, maybe.

Wanted to try. I had to open the website in private mode to see the sign in popup (note that on the sign in button, it is witten "sing in"...) Received the email, clicked on the link in the email: It open the website with an error popup saying "Email is not provided".

Do the basic stuff first.

Well, today, a good example is core-js. But it depends what you mean by "understaffed".

Well, that is very easy. You just need to buy the latest Nvidia GeForce RTX 4080 16GB (not to be confused with 12GB) with TSMC's 4N process, Micron G6X Memory, Base clock speed @ 2610 MHz for a consumption of 285W.
