I actually prefer auto-loading, which lets you iterate through a package manager much easier/faster - PHP iterated through PSR-0[0] before landing on PSR-4[1], and you can always build your own (which is what most frameworks pre-composer were doing).
With Rails 7 and Zeitwerk, the Ruby community has landed on a very similar auto-loading system as PHP now[2] with constants translating to paths by convention.
Yeah, I prefer an actual module system over PHP namespaces plus autoloader. It feels like a hacked on module system tbf. BUT I do get lots of real work done using namespaces and a PSR autoloader so it works.
I do wish they would extend auto loading for standalone functions and constants though.
