I'd look over at your artificial intelligence (AI) BS.....quietly hook up the master computer on my ship one night to the AI mainframe....have the alien AI talk to the human AI....then quietly advance it by 1,000 years.
'Joe' and 'Ernie' would walk in the next day....find all this massive improvement in knowledge, and just explain to Elon as a accident.
If this were to happen....you'd see tons of technology improvements in a matter of just ten years, yet never realizing you were helped.
Just something to ponder.
