Also, supersonic air travel already exists. It's not a technical hurdle anymore and the Concorde was even profitable in her later years.
There's a lot of research addressing the very real problems you pointed out and it seems plausible that they'll at least be mitigated to a degree in the near future.
Hyperloop is a (vacuum) pipe dream. It sounds super cool, but the more you think about it, the less realistic it gets.
I've always heard that seismic activity makes hyperloop-style transit effectively impossible.*
โ Impossible given the constraints of current materials science. From what I've read (which may be garbage, but it seemed well researched), making a vacuum chamber that's hundreds of thousands of miles long on top of a big wiggly molten goo ball isn't something we can even see a way to realistically achieve right now.
I said hypersonic not supersonic
