The phenomenon that ultimately put down the Concorde is actually seen all the time everywhere in everyday life: Bleeding edge performance and tech is almost never economically practical, it's always the stuff well within the margins with room to spare that ultimately define the space.
See for other examples: The 500 Kei Shinkansen, literally every Intel Core i9 and AMD Ryzen 9 CPU, sports and luxury cars, Boeing 747 "Queen of the Skies" Jumbo and Airbus A380, the Space Shuttle, the F-22 Raptor, and more.
All very impressive pieces of tech and their achievements shouldn't be discounted, but all ultimately an interesting footnote in history as significantly more inferior and practical pieces of tech dominate.

- pavlov 3y agoThe 747 was manufactured for 50 years and over 1,500 of them were made. It’s difficult to put it in the same category with Concorde and the Space Shuttle.
- noarchy 3y agoThe 747 still has demand as a cargo plane. I bet we see them flown for a long time to come, with most remaining passenger configs gradually being converted to cargo.
- hef19898 3y agoThey do get replaced by (converted) B777s and cargo A350s so. The 747 still will have a place, especially for long and heavy loads so.
- haunter 3y ago> literally every Intel Core i9 But today’s i9 is tomorrow’s i7 and the i5 the day after tomorrow. So it has its place in the story
- alwayslikethis 3y agoGiven they are sold every generation, they must be practical to enough people. There are quite a lot of multithreaded tasks that can use so many cores.
- rsynnott 3y agoI haven't been keeping track lately, but these used to be "the i7, but squeeze out an extra 500MHz by adding another hundred watts", usually; has this changed?
- haunter 3y agoYeah pretty much that. They usually have the same amount of performance cores but there are more efficient cores and hence threads and on top of that they run on higher frequency too i7-14700K: 20 cores (8 performance, 12 efficient) 28 threads 5.6 Ghz i9-14900K: 24 cores (8 performance, 16 efficient) 32 threads 6 Ghz It's like ~10% performance difference
- aredox 3y agoIt was not just not economically practical: it wasn't practical. Yes, the flights were shorter, but between 9 hours cramped in a tight fuselage with little entertainment and 12 hours in a comfortable chair with headroom and entertainment, I would have taken the latter. There's a sweet spot abive the even more comfortable but vastly slower passenger liners, but Concorde was too extreme - and I guess the suborbital flights imagined by Musk are too far too.
- jnsaff2 3y agoIt is incredibly cramped inside. I stepped into one in Duxford museum and especially the windows are tiny, the looking at the curvature of the earth thing would have been pretty hard. https://external-preview.redd.it/K5Z9Kd7AkxJz-eQm5I97pZYIDTarvgUMacdk2DBLDo8.jpg?auto=webp&s=b44b87e22f5e90de20705c98dd2103290420e0d3 https://external-preview.redd.it/K5Z9Kd7AkxJz-eQm5I97pZYIDTa...
- ghaff 3y agoMy dad traveled to the UK all the time through JFK. He got upgraded to the Concorde once and his reaction was that he actually preferred first class on a 747--and that was at a time with less comfortable seating than exists today. Very few people really benefit from the faster flight time, especially if it doesn't have the range to do trans-Pacific. As you say, ocean liners are mostly too slow for anyone who is working but I was surprised to learn recently that they're not necessarily much more expensive than a business class flight.
- dotnet00 3y agoComparing chips in this context doesn't work, especially with Ryzen, where, due to chiplets, the effect of yields on price is mitigated significantly. They're higher margin products, not products that cost so much to make that they'd have to be priced so high.
