In the recent spaces for X.ai, Elon mentions that he can't go into specifics, but Tesla has found that the solution to AGI was much simpler than they initially thought. He goes on to stipulate that they'll still need a lot of compute and they're not trying to solve AGI with a laptop, but he reiterates that they've discovered the answer is not as difficult as they thought it would be.
Listening to this I had the feeling they've made some serious advances and with the impending ramp of DOJO, I continue to be excited for Tesla's future.
