in AI era, marginal cost of getting your 'anything' compatible with open systems and solutions is so low, that soon I expect only really stubborn, sad people still fighting with MacOS/Windows/PadOS
Define soon? I'd put a lot of money on the current crop of OS's still being dominant in 10 years. Most folks don't care enough to switch let alone "vibe" their own replacement software.
As much as I wish 2027 to be the year of Linux Desktop, I'm afraid the companies will just "up the ante" by making all the APIs and boundaries much more convoluted, with AI watchdogs and remote servers along the way.
No non-technical user in their right mind will be trying to vibecode an OS and flashing it to some random off-brand tablet anytime soon.
