Haha yeah. I get where they were coming from though. The 1st half the century saw an incredible explosion of scientific and technological progress. Intercontinental airplane flights instead of weeks on a ship. Electrification of homes. Television broadcasts. Eradication of entire terrible diseases. Massive progress on so many fronts.
It seems natural to think the same rate of progress will continue. So… sure, maybe another decade before we get cars that both have radar and fly and float? And that’s a thing we could have done by 1964, on a one-off highly impractical basis. It just couldn’t be economic or practical at scale.

I do not want to be the first human test subject for the sinus nanobots.
