Full Autonomous driving is definitely also a very ambitious project. I do think it is in principle feasible, and has great potential,

Problem is he promised it was basically ready in 2016, and would be available for customers "next year". Yes "we" will eventually get there I think, but it will probably not be Tesla.

I do think Musk is a narcissist, I don’t think he is an idiot.

I agree, He is mostly an idiot because he can't help being a narcissist, it makes him behave irrationally with over confidence.

I also don’t think he is a genius, more like someone with decent amount of technical competence

Exactly, obviously he has some sort of competence running a business, but you can be both competent in one way and an idiot in others at the same time.

I don’t think that takes away much from the actual achievements of both Tesla and especially SpaceX however.

Yes I admit the success of Tesla is a huge achievement, and I too defended Musk for making the electric car cool and also show it was feasible. When the critics began. I still admit that's a significant achievement, but today as ThunderF00t says, just because he may have been a net positive, doesn't mean we should look the other way when he does harm later.
