The technology is nowhere near ready.

Let's see Musk deploy Optimus robots in a Tesla factory, which would be the zeroth step in a billion-item checklist before they're ready to build one of themselves from scratch. Tesla already failed to roboticize its car factory, which should have been easy (since it's the same task over and over).

It's especially rich coming from Musk, who has a long and nearly unbroken track record of big announcements that come either very-late or never.

I'll worry when somebody other than Musk is on track.
