I don't think anyone sensible is writing Tesla off. But, they were significantly overvalued (still are, but not as severely), and they have some serious issues ahead of them - such as quality control, the FSD debacle they've walked into, and certain members of leadership currently in public fights with regulators. I think Tesla is here to stay for the long term, but they certainly haven't made things easier for themselves.
