> Isn't that basically one of the ways doing innovation? Instead of saying "No, that's not possible" when someone asks if they can build something faster than a horse and carriage, a bunch of people get together to see if there any way of doing that, trying to avoid any per-concieved ideas about if it's actually possible or not.

This does not take real-world limits into account. There are limits to information theory (which includes crypto), thermodynamics and mechanics that make certain things generally impossible. Like a perpetuum mobile. Social or intelligence factors do not matter. Knowing your field also includes understanding those "hard" limits.
