> Number of times I have had the problem of "email not working for some reason" since switching to gmail ~20 years ago: zero.
This is incorrect. By using Gmail you've lost several legitimate incoming emails due to their horrendous spam filtering. It's just hard to be aware of the emails you've never seen, so you think nothing ever failed.
In addition, if you are relying on @gmail addresses, you run the catastrophic risk of permanently losing access to your email with no-one to call for help. There's so many instances of this happening that you can't even call them isolated instances. All it takes is for Google's ML algorithms to think that you have violated their T&C somehow. And poof! Everything is gone.
