Good for you. I started in 1988 myself.

So if you consider that the ``su'' command was in UNIX First Edition (
https://en.wikipedia.org/wiki/Su_(Unix) ) in 1971 (
https://en.wikipedia.org/wiki/Research_Unix ), but ``sudo'' has been
around since 1980 ( https://www.sudo.ws/history.html )...

If it's that old, it must have filled a need.

And if it's now used  by default and ``su'' is deprecated, and has
been since the release of Mac OS X in March 2001 and the first release
of Ubuntu in 2004, hey, don't you think there must be a *reason*?

These days root has no password and can't log in, so ``su'' is no use.
You are urged to prefix commands with ``sudo'' instead. Why?

It's more typing, so logically there must be a benefit.

Others have explained that benefit to you. You've ignored it, and 37
years of OS research, and are urging people to do it 1971 style  by
abusing sudo to run a shell.

Why?
