I don't disagree with anything you said there! In fact I agree with your measured take. I only wanted to push back against this part from your original comment:
> At that point Tesla may become no more than Dachia or Kia.
The future is already here, and it requires these old car companies (Ford, GM, etc) to not only become electric car companies, but also become computer hardware and software companies. Many many manufacturers will fold in the coming years or be absorbed by larger conglomerates because they simply won't be able to compete on these vectors.
The advantages/efficiencies these old car companies have spent decades building are being rendered irrelevant. And that's the real problem for them. The risk isn't that they can't compete, the risk is that whatever they put out is irrelevant. Think iPhone v. Blackberry.
It's not just about making a new type of car. It's about building a new kind of company entirely.
The worst case scenario is Tesla gets acquired for a godly sum of money - not that it goes under or becomes the next Kia. Tesla's battery production capacity very well makes the company one of national strategic interest.
