I learned a bit of rust and I think it’s just about getting used to it. It’s fairly subjective, and people say the same about C++. I also prefer the C syntax because I find it’s simplicity extremely elegant and prefer it to have fewer features. And I like it for it’s consistency, on linux the FHS is based up on C, and it just somewhat feels ugly to break that consistency.

But I also acknowledge the advantages of rust.

Yeah, I don’t think there’s anything wrong with coding in rust for people who like it. But I do think it’s quite a bit of useless work that could be spent more wisely on new products instead of rewriting things that we already have

It is possible, it would bring in quite a few restrictions though. The bigger problem I see is that it wouldn’t be entirely clear as an end user whether a program is memory safe or not. However, this isn’t the case with rust neither. Maybe some kind of certification would help

not a big fan of rust personally. I think it would be much smarter to bring borrow checking to C through annotations. That way we would not have to rewrite the whole world

I self host my mail. There are plenty of people telling you not to do so, but I sincerely have made very good experience with it the last 10 years. The absolute minimum you should do is to have your own domain, otherwise you are in a vendor lockin.

Then, use PGP where possible with an open source mail client such as thunderbird.
