As a car enthusiast, I can think of a good one, the Ford Nucleon.
During the 1950s and 1960s, there was considerable interest in nuclear power and its potential applications. This led to the idea of using nuclear energy to propel cars. The concept behind a nuclear car was to utilize a small nuclear reactor to generate steam, which would then power the vehicle's engine.
Of course back in those days, this was extremely futurustic and some at the time thought this would be a game changer, but ultimately, the safety aspect was one of the biggest reasons why this idea was dropped, and I probably don't have to explain why it may not have considered to be safe, I mean, it was using nuclear power, so even if the engineers tried to make it as safe as possible, IF something went wrong, it would have been catastrophic.
Ever since then, the interests in the automotive sector has shifted to Electric and Hydrogen.
Still, a very intriguing concept car and idea.
Outside cars, you have blimps, and I personally believe if we tried to make something like a hindenburg today with existing technology, we might have been a lot more successful than back then (as it goes way back to 1930s), there are still some blimps used occasionally, I also don't believe those use hydrogen(?), but they are not the "game changer in air travel" it was once seen as, although we can't rule out a comeback.
What about you guys?
Back in the Windows 8 days, Microsoft tried to push Universal Windows Platform (UWP), a new application format that could run on any devices running Windows 8: desktops, laptops, smartphones, tablets and even Xbox without any modification while being much more secure by default.
It failed for a multitude of reasons:
UWP still lives on in Windows 10 and 11 as well as in Xbox One and Series: many system apps are now UWPs, as well as all Xbox games and apps, some cross-devices games from Microsoft Studios and some apps in the Windows Store.
Maybe I'm a curmudgeon, but I hate using "apps" on my desktop machine. They're always designed to be friendly for touch interface and smaller screen size, and are terrible to use on my 30" monitor with a 1/8" cursor. I just want my menu bar, toolbar on the left, and status on the bottom, please and thank you.
I hate using most apps on my phone. It's not that I'm a curmudgeon. I'm a developer, and I don't see any good reason for so many damned apps when a browser works just fine.
You'll always get asked about apps whenever a new service or whatever is launched. Even here, there're people asking for a Lemmy/Kbin app.
The worst offenders are the ones who make their mobile site impossible to use so you will download the app. Unmovable banners, incorrectly sized floating menus, and features unnecessarily locked out unless you switch to Desktop mode or use the app. Guess what, I'm definitely not installing it now!
Nah, you're not. It simply is not possible to have a single UI that works just as well on both a touch-driven 5-inch interface and a pointer-driven 20-inch interface. Different input methods require different UIs. But publishers are lazy so they try to pretend you can.
