Correct! We have been repeating ourselves ever since we first realized we could do science with sticks to wield energy.
Sticks make fire, fire makes better sticks, better sticks make better caves that fly and shoot fire (give or take a few steps). The principle concept of shelter and energy is so fundamental it's caveman old and we still use it. Our imagination can change what it looks like as time goes on, which in that sense, makes it no longer "prehistoric" as quoted but it is still wielded by cavemen, albeit well dressed and better educated cavemen.
I believe the day we change ourselves in to something that no longer needs or wants "caves or fire", we will no longer be cavemen in that sense because we will have become something that is alien to the original reason fire was needed. We may not even be human at all anymore. Until that time, we are just cavemen that have had a long time to make better sticks and more efficient fire.
Oh and also my cavemen statement was just to poke fun. I agree that "firepower" can be used universally, "phaserpower" sounds more Star Trek themed which I think is what Ahobgoblin was going for.
