Interesting and thought-provoking.

I don't think Rust is mainstream enough to be what they were attacking, especially 6 years ago or whenever Blow gave that talk. Unity certainly is, and they seem to reserve special scorn for it, maybe because it's so popular.

I don't agree that it's easy to make Mario hit a stable 60fps in any popular gaming environment. In the browser, it's easy to hit 60fps but impossible to keep it stable. And, as you concede, it can be challenging with Unity (or Godot).

Latency is a separate issue from fps, even when the fps isn't janky. With your PC plugged into a Smart TV, you can hit a stable 60fps, but typically with two or even three frames of lag from the TV, which is a very noticeable downgrade from a 6510-based Nintendo connected to an RF modulator and a CRT TV from 01979. And often the OS adds more! Three 60fps frames of lag is 50ms. The one-way network latency from New York to London is 35ms. Most players won't be able to identify that there's a problem, but they will reliably perform more poorly and enjoy the game less.

I'm skeptical of the Muratori crowd's implicit assertion that this kind of responsivity is inherently something that requires the game developer to understand the whole technology stack from SPIR-V up. I think that's a design problem in current operating systems, where it definitely does exist. And, while I'm skeptical of their dismissal of the importance of bugs, I'm confident that they're representing their own needs as accurately as they can.

But probably it's better for you to engage with their explanation of their own ideas than with mine. I might be misunderstanding them, and I don't have their experience.
