The failure of our times has been just this. Not realizing that when what you are doing has global impact you need to think hard about its effects and be crystal clear on the ethics of it all. Perhaps the original sin was not pushing for more hands-on ethics training for every child and college student.
The Kyoto Protocol was in 1997, but the US didn’t ratify it because the API managed to influence US politicians enough to cast doubt on the problem.
Granted, NZ's a small country, but if it was known about there pre Great War, I suspect many people knew about it elsewhere too.
It is one of those things that until very recently had been quite easy to ignore though I suppose (and many still try even now).
We went fromom electricity to flight to nuclear to space flight to the internet in less than 150 years.
Its been less than 100 years since antibiotics were invented, so, sorry we aren't addressing antibiotic resistance at a fast enough pace for you.
Hope you don't mind all those vaccines that are keeping you healthy and providing here immunity: they've only been around for about 130 years.
It's the most innovative time in human history, despite your negativity.
1947?
Concorde was testing by 1969, but didn't carry passengers until 1976.
The USSR's Tu-144 actually beat Concorde on both dates -- 1968 and 1975. Though it also beat Concorde, by 25 years, on retirement from passenger service: 1978.
Interesting though you cite mainly engineering achievements, I had a similar feeling that we are in a phase of engineering/materials advancements, particularly sub-microscale in the post-WW2 period. But having said that, technological advances of this kind tend to end up as historical footnotes, no matter how amazing they seem at the time.
I think vaccines and antibiotics are probably our era’s truly great technological advance that kids will still learn about post 26th century. But quantum mechanics and relativity are really our Pythagoras’ theorem equivalents, and will stay in textbooks for a very, very long time.
