The exceptions being Tesla and possibly Rivian and Lucid. With Tesla you know that Musk will find a way to keep going either by hook or by crook. Rivian is in a more uncertain situation but they have shown that they have the mindset of a SV company like Tesla and so we can't write them off yet. Finally Lucid seems to have a large well of cash from the Saudis so they may stick around as a niche maker.
