I simply HATE these new computer operating systems!!!!!!

I feel your pain.
Do a search for how to disable "Autofill" on whatever OS you've got. It's one of the first things I do on a laptop, phone, whatever. It's extraordinarily annoying and usually wrong.
Remember, these AIs are being programmed by a generation that doesn't give a hoot about spelling, punctuation, grammar or syntax- so the AI will probably get offended when you disable the program. Just sayin'.
