But, I don't' think humans are that useless to where they're going to fail in fixing this. This can be reversed and we're in the beginning stages. The hole in the ozone layer was deemed doomed and without repair. NASA has it in track on being fully recovered in around 2060 since we stopped using shit aerosols in the 90s.
I think Musk is a complete and utter cunt, but I also recognize the good he's done for electronic cars. Now, all the big players are releasing real electric cars. Hell, VW is doing so to fix their PR image after the diesel scandal. This is good. Still will take time, but you can't have a critical mass breaking point without a slow beginning. A point will be reached (when, I'm not smart enough to answer) and fossil fuel cars will look like a home phone compared to cell phones. If you're old enough, you'll remember that cell phones were "secondary" phones. Then, in a flash, people realized "Oh, we all stopped paying for landlines". And few people have landlines anymore.
The moment Dodge/Ford/GM come out with an EV that has the same feel and balls as a muscle car, that's my personal breaking point. Right now it's all focused on the luxury, feather, Italian aesthetics feel. Fuck that dumbass nonsense. Give me a mean and angry electric vehicle. Or an ultra long range EV Jeep. That'd be cool.
