Everything old is new again

Hey, so you guys know how we haven't really invented anything (no, smaller and more technologically complex versions of stuff that already exists like phones and computers and cigarettes don't count) in a really long time, like how we're still almost entirely reliant on technology from the 1850's to power our vehicles? Well, who has time to waste on that shit when new, colorful packaging and an effective marketing campaign suffice just fine?
The other day a companion was really excited to tell me all about Mio, the flavor additive you put in water to make it taste different/better. Or as it says on the little bottle, it's a 'LIQUID WATER ENHANCER'. "It's fantastic!", she said. "You just take a bottle or glass of water, squirt some Mio into it and it becomes flavored. And you can put as much or as little of it in the water as you want, depending on your individual taste preference. It's amazing!" I stared at her for a minute and then asked, "Is it? It's something that amazes you? Is it really fantastic, in that it's extraordinarily imaginative? If I'll bet it's also awesome, as in it inspires awe!" "Yeah, it is pretty awesome. I don't know why somebody didn't come up with it before. The people who did are geniuses and are probably going to be millionaires." "I don't doubt it", I replied while providing positive feedback to her unbridled enthusiasm for this pioneering effort into the previously-unexplored frontier of LIQUID WATER ENHANCEMENT. Then I asked her, "Have you ever heard of Kool Aid?"
