I think that eventually one of these solid state battery technologies will work out and also will be able to be manufactured reasonably cheaply. It seems very likely that manufacturing existing EV models will be pretty easily convertible to use whatever new battery technology shows up on the market (changing out the skateboard perhaps - not nothing to change but not that hard). Toyota says they have it figured out but their new EVs aren't coming until 2028 model year (5 years!). But this kind of longer timeline also hides the failure of a lot of car makers to invest enough in the battery supply chain - they can't buy enough batteries or they are too expensive, so it's another excuse for what they want anyway, which is not to make that many EVs. They want to keep selling ICE cars while they can.
Look at GM and Ford, the GM ultium battery pack has unspecified problems with mass manufacturing, Ford has also slowed down manufacturing at times this cal year (to improve efficiency or something, specific reasons unclear). I still see the market dynamics being that (1) Tesla continues to take market share from legacy auto where ever they are on the market, and (2) Chinese companies will follow and be even more devastating, because they are making EVs in even larger quantities, decent quality and low prices.
