echnically, they could do it now, if Adobe or whoever chose to make it available.
It’s not a lack of power or RAM that is the problem, it’s a lack of demand.
Take Unity, for games building, I mean who actually wants to run that on smartphone, with the absolutely brutal lack of usability it would involve? Tiny screen, no keyboard, no mouse, it would be horrendous. No actual game developer would use it.
So Unity would spend a lot of money bring it over to Android, nobody would use it, and they’d stop bothering to maintain the port after a year.
Modern smartphones are as fast as maybe a 10 year old laptop, or even faster than some *new* laptops. The problem is hardly anybody wants to run desktop software on a tiny smartphone.
You get some phones that plug into a screen, keyboard, mouse etc. to give you a very slow and expensive desktop, again, hardly anybody is actually doing this.
