If you're going to make a 4 letter comment, at least be correct. Tesla in no way could be thought of as "short-term popularity." Every year, they've had increasing sales, about +20% between 2022 to 2023, and their latest quarter is still the highest sales of any quarter, on track to make $100 billion annual.
Yet, as mentioned elsewhere in this same comment chain, they're almost certainly overvalued and in a bubble. Not only that, but their overall image has suffered over the last few years thanks to Musk. There are plenty of concerns over their inability to produce a product of actual high quality that doesn't consistently fall apart, and their product line is stagnating without any new cars (cars, not Cybertrucks).
It's cool that sales have increased, but so many other signs point to their run being relatively short-lived that it's not an unreasonable viewpoint to expect them not to be as strong as they are long-term.
Edit: Hell, even Musk has said they're not a car company anymore. Can anyone actually tell me what kind of company they are, then? How can I expect for them to be as successful if they're having some kind of existential crisis, for lack of a better word? Good luck getting your employees moving towards the same mission if we're not entirely clear what that is.
Edit 2: Further, they've only been selling their current lines of cars for twelve years. That's a relatively tiny amount of time compared to other leading manufacturers. That's short, and all signs point to them not really knowing where to go from here. Just because there's been growth doesn't mean it's guaranteed to continue. Downvote this comment too, disagree with it, I don't really care - time will tell how this shakes out.
