I'm kinda curious about this too. But then I'm always amazed at the enormous workforces these tech companies have, and I'm sure they cut them as thin as they can. Like adobe has 30,000 employees & some blogger estimated that 1/3rd of their workers are actually working on their software. I use their software sometimes and I really haven't noticed many changes to it over the years, except recently with the ai stuff. Like from 2015-2020 I can't think of any major things they added to adobe illustrator. I guess making and maintaining software is hard.
