I'm almost excited to blow another hundred billion dollars on designing a next-gen aircraft without any G-Force considerations. Current jets designed around a human pilot can already achieve mind-boggling performance of over 10G on multiple axes, what would a blank slate aircraft with none of those limitations be able to do?

Not that much more, but you'll be able to control the aircraft at all times because the 'pilot' doesn't black out in high-G situations. Maybe save a little bit of weight, smaller radar cross section.

You don't think there'd be a bunch of compounding design decisions available to engineers? Pilots currently black out in high G situations so the flying envelope is basically constrained to acceleration / turning radii that are at the edges of pilot abilities. Sure if you removed the pilot in current planes, you'd be able to hit the extremes of that envelope, but if you were to redesign it without ever thinking of a physical pilot, you could have a much wider envelope. What would they be capable of?

Something like this but with a ~full-size airplane:
