I can't agree more our startup is working on time travel there's no doubt that if the technology works, it would be a game-changer. Since it's a purely technical challenge we expect to raise a trillion dollars in our seed round.
I should point out that time travel would fix the phone charging problem quite handily. Just send your phone back in time a few hours. Not sure if there are other applications.
You don't even need to do this - if you need a trillion dollars then just get in your time machine once it is built, head back 25 before today and invest $1 in all the hot stocks and winning lotto number so that by today you have the trillion you need to build the time machine. Simple.
And if not, pivot to perpetual motion, like this chap:
