technically there is a lot it could do, but it would not be a number 1 pick for any of it (even if you only have a $100 budget) so i agree, get rid of it.

There is already gridcoin which is a cryptocurrency that awards boinc work, so I’d say this concern has already been addressed because of that.

xpra: it is like tmux but for X windows (works on wayland), but it can do much more than that. You can seamlessly run GUI programs from a container or VM on your main desktop while still sandboxing their X capabilities, forward windows from Windows desktops, and it has efficient encoding so it is usable over poor connections as well.

I don’t think tar is actually hard, we are just in the time where we externalize more information into resources such as Google. Its the same reason why younger people don’t remember routes by name or cardinal direction as much anymore.

side note: $ tldr is much better than man for just getting common stuff done.
