This deserves to be expanded on: I very much see the need for innovation in OS research. But I just don’t see anything in BeOS/Haiku that would address any of the big challenges for operating systems. Which in my mind include the following:

Can we get away from the “leaky bucket” security paradigm where despite all of the best efforts and gradual improvements, prevalent operating systems “keep on giving” in terms of exploits that are discovered all the time. Is there something akin to what Rust is for programming languages?

Or what about an operating system for AIs? Is the current stack of Linux, GPU drivers, and some ML SDK on top an adequate answer for emerging AI applications?

Or if you still believe in Blockchain applications, what about a native OS for that?

And the list goes on.

All I see in Haiku/BeOS is a pretty, albeit dated user interface. Someone educate me what else they bring to the table.
