Side note: Sorry to spoil the apparently impeccable record, but for completeness:

A half-century ago, civilians could experience supersonic flight. Well, it has since become impossible.

A half-century ago, people walked on the Moon. And not once since.

Just a reminder then that unfortunately the passage of time alone is insufficient to guarantee technological progress. Now, let's get back to work, I guess...

Absolutely. I wonder if say, cheap energy, will be as readily available for non gov / army purposes in 50 years.

The comment your responding too sound like someone born in the 60´s or 50’s. ( meaning : tech is always progressing, no limit, forward and upward . It’s nice. But I don’t think it match 2023 )

Energy is available more cheaply now than at any time in history, and the cost is still falling at an exponential rate.

You can just set out a solar panel and collect hundreds of watts. The only way that could be lost is if civilization collapses so solar panels can't be made anymore. Even if that happens, most of humanity would quickly starve, and whoever is left would find plenty of panels to salvage.

you are right about this, but my argument is that we can do this if we want to. Whenever humanity set its sights on a big project such as Apollo or Manhattan, we have accomplished "impossible" things.

Human history is one of both pessimism and optimism. Definitely the optimism of the US in the 1950s and 60s was helped along by the destitution of the Great Depression (1930s+) and WWII. And there was still a lot of suffering and reason to be pessimistic in that time. (And the 30s were a direct result of the 20s.)

I’ve also seen the studies on human cycles suggesting a link between how long ago a period of massive suffering occurred and the propensity for people to entertain ideas likely to bring about great suffering. Simply, people unable to forget the horribleness of war will fend off the little and big things that can lead to war much better than people who have never seen war.

I hope humanity can regain some optimism and direction without having to go through a world war. Or similar.

I find it worrying how much modern fiction is dystopian. I would call Game of Thrones dystopian, for instance, and it was immensely popular. Utopias like Star Trek are often ridiculed, for counterpoint.

Granted, internet comments are generally worthless. The signal to noise ratio in HN comments has gotten extra horrible of late, for that matter. It could be just the low lying fruit for people to get upvotes. But it degrades the site.
