As someone who dealt with not having internet on a computer before, I’d say it’s pretty limiting these days. You can do stuff but only if you know how to do stuff to begin with. And the software preloaded on some OSes isn’t exactly enough to keep you entertained for eternity.
If you don’t know how to do things then not having internet is pretty limiting. After all, most software out there doesn’t come with robust documentation built in. It’s been all online for a while.
You might be idolizing your younger years when there were quite a few pain points that you’re glossing over. If you don’t like certain parts of the internet then don’t visit them. It’s not like you’re forced to be on social media. It’s clear from people I meet on forums that they don’t go almost anywhere else but that forum...
Only expensive software came with instruction manuals (embedded instructions weren't a thing) but when they did they were leather bound. You really had to figure things out yourself.
Let's say you had a c64. You have no software installed so you have to type in a program or possible load one from a disk. Completely different mindset.
Fast forward years and you have lan doom parties. Everyone goes to a store and plays on a hardwired network.
The internet is great.. there is life outside of it if it disappeared.
No internet means fewer distractions and one can do deep work, but this is not permanent. Internet is good but in moderation, too much of it and it starts consuming us.
