Been in an Internet blackout experiment for about 7+ days.

No phone, no TV or radio either. Electronics yes, computers yes.
Been a very interesting experiment. Saying this as a dude that lived a couple of decades before the Internet and mobiles era. Highly recommended experiment.
From a pragmatic point of view, been surprised how many programs complained for not being able to go online!

Arduino IDE, for example, only complained, while VScode python addon simply didn't start, had to use IDLE. All this activation and/or phone home trends is a plague even for free and open source software.

Then, you'll find a strange feeling of not heaving online search and/or downloads available at your fingertips. Partially been saved by the personal library. Similar strangeness came from the lack of live content, being it the lack of social media or the lack of live AV streaming. When you are offline, playing a recorded movie or album is not the same as playing the same thing from the Internet.
Regarding programs docs, many don't install more than a man page by default. However, for those who have offline docs, reading the manuals proved way faster in getting things done than searching online. That, you have to use what ever you happen to have offline, either books or software.
Overall an interesting, fun, and sometimes challenging experience, try it if you can get yourself an isolation week.
