Once you have that initial back up you can set your replica and make it catch up , then you switch. I choose to take the few seconds of downtime doing the switch because for my use case that was acceptable.
If you’re migrating a large MySQL database and you’re not
using mydumper/myloader, you’re doing it the hard way.
If you aren't using xtrabackup you are doing it wrong. I recently migrated a database with 2TB of data from 5.7 to 8.4 with about 15 seconds of down time. It wouldn't have been possible without xtrabackup. Mysqldumper requires a global write block, I wouldn't call blocking writes for hours a "zero downtime migration".You can also drag and hover while waiting for the opponent move and release if the expected move shows up or right click to cancel the drag if not the expected move.
Also dragging and hovering over your target square is super useful to visualize your move and catch any last millisecond mistakes.
I do t think any of the top bullet/hyperbullet players does click and click. I think I have seen Magnus doing click and click in very old chess24 blitz videos but I’m not sure he did that in lichess playing bullet orin chesscom scc for example.
A perfect example is chess. It used that a lot of knowledge was in books, often in foreign languages. Nowadays everything is out there in the open and additionally you can casually play games against top 100 opposition once you are okeish enough accelerating the development even more.

I wonder if he even knows about smartphones.

The authors of the paper suggest a +0.15 Wm−2 radiative forcing and give the radiative forcing increase due to CO2 form 1996 to 2005 as +0.26 Wm−2.
This seems to provide an explanation of a huge jump in temperatures non expected by current CO2-only models.
Why this effect would not have been seen in the summer of 2022 I don't know, nor seems the authors of the paper or the liked article address it.
Also the author says this effect may dissipate in 5-10 years at which point the expected warming from CO2 would "match" the current temperatures anyway so there's no real 'cooling' to be expected.
