The biggest case of buyer's remorse in US history. Musk's purchase of Twitter.

I would say that Musk's purchase of Twitter (now X) is the biggest case of buyer's remorse in American history. A problem with Twitter is that it is too much about sound bytes brevity and speed. Not a good environment for nuance.

I've been somewhat of a fan of Space X and hope that Musk and the Twitter debacle didn't bring down Space X as well. Who knows. Space X has some good achievements, but there is also increasing worry about it's prolific launches and satellites interfering with astronomy.
