this is why I said it was huge that the one robot could change its own battery and once it could do maintenance and repair on one of its kind its going to be an even greater leap. I don't think that is very far away. Honestly the thing likely to sink it is enshitification where all repair parts and such will only be through a contract and maybe only authorized units will have the repair code and they will send one to your place with your monthly subscription. Which im like 99% sure will happen.
