Quantum computers were never supposed to replace conventional computers. Their theoretical performance is only superior for a specific set of problems that usually are not relevant for every-day computing.
You need to understand to correctly classify the danger though.
Otherwise you make stupid decisions such as quiting nuclear energy in favor of coal because of an incident like Fukushima even though that incident just had a single casualty due to radiation.
winget is a poor excuse of a package manager, misses lots of applications, doesn't handle OS updates and AFAIK also no dependencies.
WSL is Linux on crutches since the file IO is done with the subpar Windows API and bloated NTFS killing one of Linux' most effective performance advantage (it runs much faster in vm on Windows even). It's basically the reverse of Wine which makes some Windows applications run even faster than on Windows itself.
if someone grows up with specific OS, they will probably prefer that OS and when comparing it with another one
Cannot say anything about probability but I grew up with DOS and Windows (starting from 3.1). I tried Debian in the 90s and hated it. Tried again almost 20 years later and eventually moved all my machines to Linux (Windows 10 telemetry was the last straw). Still use Windows at work though and hate it even more now that I know how smooth a modern OS can run.
It’s good enough for NSA to catch a terrorist, not necessarily useful enough for FB to produce targeted ads.
I disagree. Identifying a terrorist and their whereabouts for targeted assassination is not that different to serving personalized ads. It's all about gathering information about the person.
True, file metadata is unaccessible like message content but I was referring to message metadata which covers ip address and phone number (as you mentioned) but also geo location (possibly live - WhatsApp is an application after all), when you communicate with whom how often. You can derive lots of info from that especially if your communication partners are more careless about their data and may maintain an active social media profile with Meta.
It's definitely easier than finding out info about someone whose life depends on not being found - like a terrorist.
if you don’t have a FB account, or don’t use your real name there, all they’ll know is that you have a WhatsApp account, but won’t see your messages, unless someone reports your messages
but the same can be said for other OSS alternatives;
Well, your example is not open source, so yes, you cannot trust Telegram. Signal open sourced their server code some time ago. Even with FOSS you have to stay vigilant though and complete trustlessness is hardly achievable (do you trust your device? Your carrier? Your communication partner's? Etc.)
I've never played tabletop RPG but to me such people just sound like they want to be an asshole and only feel safe enough to play it out ingame. This doesn't seem to be really about the game.
