Another question piggybacking off of this one. Why do we still use electricity to do stuff? We’ve been using it for like 200 years and to my knowledge nothing else has been developed. Can’t we use some other force of nature to do our bidding? Just think it’s kinda crap that everyone always complains about how we generate electricity and moving to green energy where if we developed something that wasn’t electricity to do stuff for us we wouldn’t need to produce it anymore.
