What has Tesla accomplished lately? I mean, within the last decade?

They certainly have accomplished amazing things. They had a lead that even five years ago was considered insurmountable. But they've made at best incremental progress, the kind made by mediocre engineers. The only novelty was the Cybertruck, which didn't live up to expectations and didn't open up any new domains.

SpaceX is still advancing, though even that is getting a bit of an asterisk if they can't get Starship to fulfill its promise.
