OP isn't saying peanuts are a poor source of nutrition. OP is saying a few peanuts are calorically dense and it is easy to consume hundreds of calories through seemingly inconsequential amounts of snacks and drinks.
Calories isn't everything, there is a lot more focus these days on how different foods affect metabolic hormones affecting satiety, blood sugar, etc. On those metrics, fat alone (which account for most of the calories in peanuts) is very satiating and does not trigger a later blood sugar drop (which causes cravings). That's why people on a diet drink 'bulletproof coffee' (coffee with butter in it), because it is extremely filling while not making you hungry later.
In these commercials, it wasn't the technology itself but the ease of access and visualized integration of these technologies into the commoners' everyday lives that was the new idea.
"Our vehicle, called a seaglider, is an all-electric, wing-in-ground-effect craft that operates within a wingspan of the water's surface and couples the speed of an airplane with the operating cost of a boat."
