My cynical take on them cancelling the model 2 in favor of robotaxis is that they've (temporarily?) given up on being a car company. They're hoping a new influx of capital after going all in on AI hype will keep them afloat.
Given that the Cybertruck is a laughing stock and growth/profits from China are in bad shape, they may actually be doing the right thing if the only goal is to stay in business for one more quarter.
