We got this nice feature a while ago now. It deserved to be used more, and it keeps improving.

Nice chapter to better understand Rust dyn traits (also called trait objects).

Yes, this one feature in the standard doesn't seem to reap much benefits... It's sad that it got there.

Databases do improve and provide more "cache like" features, but such caches are still needed for the time being.

This is a widespread syndrome. It's not only in our industry of course but has real consequences in terms of leadership.
