Big tech will do what is best for extracting money customers and investors.
If you really care what your operating system is made of, use Linux.
In the near future, probably within 12 months, all the standard features of Windows will be gone. The won’t be any Explorer, there won’t be any Start menu, there won’t be any opening screen.
There will just be a prompt and you say “computer, open yesterdays word file”, like in Star Trek. There won’t be any “apps” to install - you’ll just say “phone, open the order menu for Boise City Chick-Fil-A” and it will navigate automatically to the page.
Sure, if you’re a total weirdo you will be able to install a bash shell and navigate manually, but hardly anyone will do that.
BTW, AI is being introduced into Linux as well.
