Yes, but a computer is just a paperweight without its software. Also, increasingly the hardware is being specifically designed and optimized for that non-deterministic software. The experience of using computers is changing and we’re still in the early days of that shift.
Of course there’s still plenty of deterministic software you can run… for now.
I can almost guarantee that all of AI runs on deterministic hardware and software. AI is just (near?) the top of the stack. There is no reason, and probably never will be to have a purely heuristic computer. Deterministic systems are way simpler and cheaper to handle very routine well defined tasks. Even AI authors code behind the scenes to process data files deterministically.
If you are tying to work around your firewall because it isn’t yours, that’s not a legitimate use.
On the other hand, there is plenty of badly written networked software. I bet most of the networked software developers have no idea how to correctly plumb their software. They just open whatever connection, e.g. sockets, their OS provides and just run with it without care of the underlying layers. The OSI model theory in fact encourages this ignorance.
