The mainstream idea is that Twitter is important, but I haven’t seen much reason to agree. Most apps that rely on it could be served with an RSS feed. Most people I’ve met don’t use Twitter to any measurable degree. The amount of real world change the service has brought is rather low given how often it appears in mainstream media. In fact I see TikTok do more to influence and promote.
it's similar to tiktok. you likely don't realize you're seeing something only because it originated from tiktok or twitter. if the daily news is still regularly reporting about things that happen on twitter, then i'd say it's still an important platform.
