I switched to Ubuntu last week for my desktop. First time in my 25+ year career I’ve felt like Microsoft was wasting my time more than administering a Linux desktop would take. The slop effect is real.
I've used Kubuntu for several years, wife too now which is an official, supported flavor of Ubuntu using KDE desktop instead of Gnome. It gives a more Windows like or CDE (Common Desktop Environment - from UNIX systems) feel than Gnome which gives a more Mac feel.
You might want to change to Debian or some other distro more radical.
Linux kernels will all eventually be permeated with AI-gen code as well. It will just take longer to see and feel the effects.
You won't regret. I have been using debian for last 25 years on and off and for last 8 years non stop. I have no complains.
