I heard a good podcast about pony recently: https://corecursive.com/055-unproven-with-sean-allen-1/ - it’s about how Wallaroo Labs came to use it. They talk about using it to deal with some really interesting engineering challenges. One of the things that I found interesting is their comparison to Rust was that at least at the time Rust didn’t have a comparable runtime to Pony’s high performance actor based one.
