Lithium is here to stay for a while because it has the best ion mobility of any reactive metal. Sodium is much fatter and slower, but might be good for grid storage.

So now it should be a golden age to be a chemical engineer or a physicist specialising in battery technology research I suppose.

Chemical Engineers and Battery Technologists will be the new 'Software Engineers'.

As a chemical engineer who did my Ph.D in Li-ion battery anodes, I switched to data science immediately afterward. So I wish you were right, but I wouldn’t count on it any time soon.

uh... unless that data science is on like cancer research or something please go back
