You know what I really like: MechWarrior.

I'd love to see giant robots fight rather than boring old tanks and drones....

...we could make giant robots, and there's been prototypes.

So why don't I argue that MechWarriors are just around the corner? That we're about to enter the age of MechWarriors? Leaving those cheap, simple, easy to make alternatives behind?

Why aren't I more optimistic about giant complex robots that are hard to get in and out of, and can run out of power faster???
