This is not necessarily true for all situations. Northern Europe is planning to produce a lot of electricity with offshore wind, but laying deep sea high voltage electricity cables isn’t cheap. There’s already a lot of gas pipelines that can be retrofitted for hydrogen transport at a much lower price. At a certain point it becomes viable to just use electrolysis and transport hydrogen using excess wind power instead of transporting the electricity to land and storing it in batteries.
There are also industries like steel production that are just not going to transition to electricity. Hydrogen has a place there too.
My impression is that a big part of the reason for the sudden boom in humanoid robots is that they lend themselves particularly well to RL based training using human-made training footage using VR. It’s much easier to have a robot broadly copy human actions if the robot looks like a human, instead of having to first translate the human action to your robot arm equivalent.
Nobody shipped this because previously almost nobody could use CLI tools. Now you can just ask an llm to generate the commands which makes things much more accessible
