Marketing/Sales, IT and the entire corporate culture in general is also to blame for over engineering. Everyone involved wants to advertise they know and use the latest tech. To say otherwise is bad for your future

What's weird about reading this post is that tailscale itself is over-engineered (at least on linux anyway).

I was shocked to find the number of netfilter rules in place, all of which made the normal linux routing table useless.

I think a lot of what they're doing is neat, but when you're trying to debug forwarding rules on a box running docker as well, it kind of becomes a nightmare.

Docker messes heavily with the forwarding tables as well. One or the other is fine, but mixing the two is kind of a nightmare to sort through.

Phones are way faster than before, definitely. But servers aren't. Faster, yeah, but not to the same degree as phones.

Nor is disk IO.
