Social media platforms die in stages. That "niche group of techies" are a big part of why Twitter became what it did in the first place. It's not an insignificant group.
Twitter was never consistently profitable and these moves aren't helping, and there's definitely not going to be a savior investor after Musk. The real question is how long the company can survive, even if it remains popular in general, as that was already a big question before the ownership change.
