Tabs let you define how big you want each indent to be, and spaces do not.

Spaces can too: Simply use more or less of them, to taste.

I have ADHD. Two spaces per indent makes it damn near impossible for me to scan code.

Then use four, or six, or eight, or 20. Hell, most code I’ve seen uses four spaces per indent anyway.

Surely there’s an editor out there that will automatically display indent spaces as a tab character. Or failing that it seems like it would be rather trivial create a program to convert n spaces to tabs, and vice versa.

The thing is the average person either can’t or can’t be bothered to remember even a dozen actually secure passwords, so they fall back to a couple of simple derivations of a common password, meaning each and every site a user signs up on represents an additional single point of failure.
