While still in business, X is shrinking fast (https://mashable.com/article/elon-musk-x-user-decline-in-uk-...) and sliding in the rankings, where it is well behind Reddit and LinkedIn, and even behind Pinterest (https://en.wikipedia.org/wiki/List_of_most_popular_social_pl...).
I'm not saying it's "fully dead", but it clearly lost the cultural relevance and impact it once had.
That's a two year old article and X is the #1 news app today. How can you possibly construe that as "shrinking fast" if two years later it's in the top spot literally today? It seems like wishful thinking on your part rather than being reasonable based on first principles and the data at hand, from where I'm sitting.
The ranking compiled on Wikipedia is from a couple months ago. X is now behind Pinterest, Reddit, and LinkedIn (and of course, the major social players). Also, why would it be "wishful thinking"?
BTW, on US iOS App Store, Claude today is way ahead of Chrome, Google Maps, YouTube, Gmail, TikTok, Instagram, and WhatsApp. Surely you don't think it means it's used by more people.
