It really depends on the types of programs you are writing. A lot of CRUD style "microservices" being built these days don't ever construct any complex in-memory structures, instead deferring that to databases etc.

Also many system-ish programs, CLIs and the like also don't really need complex structures or benefit from authoring them + the algorithms that traverse them in a program-specific way.

That said, I'm not a fan of Go but generics are far from the only reason why I'm not a fan and it could probably exist as a somewhat useful language without them indefinitely.
