You are right to a degree, the toothpaste will not go back in the tube. There are some manufacturers, that didn't go whole hog, battery. Ford was one of the few that was going to build both battery and ICE, smart move. All auto companies will be bit by the battery fad, but some drank the kool-aid. I believe Ford will be the first to fully recover, others, will see the Ford tail lights. In the near future, the only performance sport car will be the Mustang, as Camaro and Challenger were killed. We keep our sport car a few years, Challenger is gone, in a year or two, the Mustang will be the only choice. I hope they produce a Hellcat type Mustang, "Hellstang," Ford could not produce enough. Most auto manufacturers stock will fall, but Ford stock, could be an investment.
