In 1960, maybe. Not so much now.
BTW, those two kids in the pic? They're now in their 80s, if not already dead. And the peak delivery of what they were promised was less than a decade away, and it's all been downhill on that promised future since then. It's unlikely that even their great-grandkids will ever see a piece of what they were told was coming "someday". Civilization has been ebbing backwards since then, in more ways than not.
Futurists are right less often than weather men.
No jetpacks. No flying cars. No disintegrator rays or laser pistols. No space travel.
In fact, just assume everything you were ever told would happen that isn't already starting, is one big fat lie, and you'll outperform them by about 4 decimal places in your batting average.
The only thing their prognostications are useful for, is historical evidence of how they wished things were going to turn out.
Wish in one hand, and poop in the other, and see which one fills up first.
