I have 8 versions on my new desktop. I mostly use 3.1 and sometimes 3.0 or even 2.93 if things get buggy, but when I switch to an older version it takes me a few seconds (2.8+), up to a few minutes (pre- 2.8) to get used to the different version (some shortcuts might take longer to get used to…automatically use the new ones).
So no, I don’t get dizzy, but I have been using blender almost every day for about 10 years now…
