The article says $4B was put into solid state research/companies as of 2025 in the US alone. Seems like they are working on it

maybe, but not enough.

but if there is level 1 to 10 and the chips are level 10, from transistor to today.

the battery would be level 2-3 . if this continues the battery cant keep up with more advance tech,where energy density matters like flying cars,BCI etc .

like people are selling two same products to the same person(same time), because the battery life is bad.
