The reason nobody likes physics is that it is a wet blanket on a party atmosphere. The two biggest parties are electric cars and fusion.
Electric cars get better batteries, but we are talking energy here. Basically, we need to replace all the energy of oil and gas, and pump it down electrical lines. Can't happen.
Fusion has still not surmounted the barrier I saw a couple of years ago. Basically, you need to scale things to be useful. Everybody and their dog can fuse a pair of atoms, but what then? You need to fuse a whole bunch at once, and that's a bomb. I have no faith in operating a plant with those laser fusion pellets. The whole thing will shake itself to pieces.
The main problem is that you need compression of some sort to fuse, and the first fusion tends to blow apart the plasma, or the pellet for lasers. I'm waiting for the announcement that they have solved this, but I think someone has to discover an 'intermediate' stage to hold off the fusion until you get enough. Don't put your trumpy dollars into this.
Another big party is humanoid robots for factories. Sorry, but the future has 'dark' factories compressed into a dense cube. Amazon has this in an upper story where no humans or humanoids are allowed. AI doesn't have the brains to do this yet. Conventional factories were designed to accommodate humans.
Physics is a downer with no money. The only way to make money is to 'Sell Stupid Stuff to Stupid People'. Have fun making money!
