I dread the day the users read the manual
ISP's absolutely run multimode. That's how you get fiber into a building or between buildings. Different types of fiber all play a role in a network deployment.
Broad statements are misleading. OM4 multimode won't push 10gb at 500meters no matter how good your hardware is.
Your statement didn't specify an application!
That's not true... There are different types of fiber with different throughputs depending on the class of the cable and the length of the installation.
What distribution are you using? The common desktop environments (KDE & Gnome) have simple graphical display configurations similar to what you find in Windows.
You have accurately identified a major part of the problem. Many people are unwilling to change their habits, or don't have the patience to learn new tools.
The other element though is time, many people don't have the time to stop and learn. Especially when a problem like privacy is a lot less immediate than hunger or healthcare.
What makes you say that?
Most desktop environments have an option for auto login under the user settings. That way you only need to decrypt the disk.
Small fine tuned models seem to be where the market as a whole is headed. Even the big players like OpenAI/Google/Meta are doing this as a means to optimize infrastructure. The Qwen3 models have been really interesting to work with.
I'm not disputing the technical aspect. But due to these realities I prefer to drastically limit the services I interact with.
SearXNG is nice
Sounds like a great reason not to use their services
