I’m expecting the company to go out of business and all of the cars to just brick.

I agree that Tesla will not be able to maintain their current position, but currently Tesla is one of the most profitable car companies in the world. So chances they'll go out of business anytime soon are very slim.
That said I think they are currently about at their height, with a peek market recognition advantage in EV, earned from their first models where everybody else only made tiny lame city EVs with limited range. Now the competition is catching up and even sometimes surpassing Tesla, and the EV market is in a slump. This is a very different situation for Musk and Tesla to handle, and time will show how well they do that.
