Being a bit hyperbolic: An update moves one pixel out of place in a line-of-business application and helldesk calls roll in from core-dumping end users who simply can't fathom how to use the software anymore. OTOH, big streaming video or shopping service revamps their UI and the end users seem to have no trouble continuing to use company resources to play videos, shop, etc.
Edit: I have no doubt many large websites have better UX resources, as compared to LoB apps, but user motivation plays a big part.
LoBs are used intensively for hours on end in a busy work day, and most people's livelihoods depend on them either directly or indirectly. You grow into them. Muscle memory used to be an actual UI design goal, back when TUI's were the most common LoB interface. Not so much anymore when everything is web app and you click through the horrid UI slowly with your mouse pointer, and repeat this identical task 200 times in a day.
edit: We naturally develop a muscle memory even for the worst LoB. But they are not designed with this in mind. If they were, they wouldn't move that one critical pixel around in a mouse driven app.
Because it was designed to be manufactured using 1960s components. A lot of the parts it used aren’t even made anymore more, because they’ve been replaced by newer components
The Space Shuttles were progressively upgraded over time to address this, e.g. the early 90s upgrade of their computers which replaced core memory with semiconductor memory. If we’d kept the Saturn V series alive, todays Saturn Vs would have had rather different innards from the ones that flew in the 60s/70s
But this is why “just reuse the Saturn V” design never made sense. You have to redesign so much of it to substitute for unavailable original parts, you might as well just redesign from scratch
Because the SLS uses left over Space Shuttle engines. Once.
The Space-X approach is to use 33 Raptor engines.
I also worked at a university and that was concerning because some students would just give up whenever anything didn't go right the first time. No troubleshooting skills at all. We were moving from Google to MS and they needed to use Takeout to backup their stuff locally, just in case something happened. But we got a lot of calls because it wasn't ready to download immediately. I've heard it's gotten worse.
Compare to cars. Once upon a time, every car owner had to know how to maintain a car. Nowadays, you can get along perfectly fine having no idea what's going on under the hood.
I get that. I used to be able to overhaul a VW beetle on the side of the road with regular tools. A couple of years ago my car's transmission's computer went out on the interstate. I couldn't even get a useful error code. The shop down the street didn't have a high enough end device to talk to it. While the dealer was able to figure it out; it took nearly a month to get the replacement part. I'm car semi-literate.
