Twitter is literally being dismantled. It’s a shell of what it previously was, and does not work for organizing protests and other counter-culture due to the billionaires buying and taking it apart piece by piece.
The whole point of Twitter was reach. None of the other platforms have the same reach.
Also the other platforms are doing their best to follow twitters lead. So yes, it’s being dismantled.
Orchestra positions are often jobs that these people will keep for life or until a seat in a new orchestra opens up. There’s an extremely limited number of jobs. I had a fairly distant cousin audition for the Seattle Symphony, for the single open trumpet seat there were north of 200 applicants. It’s such an incredibly competitive field that if you walk out, you might just possibly never get back in.
