He used the words "written by software". This is ambiguous and doesn't mean AI, for example, using annotations for variables and generating the getters and setters would count. Right click and create function body for interface function definitions also.
They're exaggerating to pretend their AI is more useful than it is.
AMD or NVidia?
Most games that I play work well on Linux with AMD. Most who have problems seem to have Nvidia. Anti-cheat stuff can be an exception though so best to ensure what you enjoy works.
If you can check hardware compatibility before hand, it helps. An up to date kernel like Fedora, OpenSuse TW or Arch can help. Wine recommends up to date kernel.
YMMV. I've seen issues in migration from Gitea to Codeberg. Always test first.

I think he demonstrates global leadership in a number of things, but leadership of France on a range of things including privacy is not good.
Enshitification by owners of Audacity including telemetry. They eventually backed down, but that was after Tenacity forked off it and people started using and improving it.
