I am a professional artist who has been working with Adobe's tools since the turn of the century and let me assure you: Adobe's apps
always take forever to cold-start. Always.
I recently got an M2 Air and Illustrator loads the fastest it ever has - I'm staring at the splash screen for all of five seconds before it's ready to get to work. Normally it's been more like 20-120 seconds for the past decade. I am quite sure Adobe will find a way to make their apps take several minutes to start up on the M2.
As a consequence, Illustrator cold-starts when I log in; the only time it stops running is if it crashes, or if I need to quit it to update plugins or the app itself. If I go off and do something else for a while it quietly gets swapped to disc by the system; the instant I switch back, it gets swapped into memory, ready to get back to work.
