Ask it to divide integer 1 by integer 2. Explain to me why the CPU hands back 0 and not 0.5.

Because integers are whole numbers by design. You don’t get 0, you get 0 with remainder 1.

Blindly saying such issues can be overcome is, imho, the truly stupid statement

I’m not saying they definitely will be - I’m saying that blindly saying that they definitely will not ever be overcome is stupid.
