Super late to this but I'd take bipedal bots. That's not to say I'm particularly bullish on that idea though. Seems like it might be simpler to build purpose built robots for specific tasks. They'd probably be faster.
I'm not entirely convinced. On one hand for bots you pretty much need AGI which Tesla is near solving. On another hand you need massive battery improvement for flights to move from toy to actually useful. But also there are more than 1 eVTOLS that already been certified for flight.
Bots would admittedly be far more useful in helping with tons of various tasks (I'm sure each task will be a subscription), but eVTOLs would unlock new capability.
