Before there were blue LED, the indicator light for full beam was a blue tinted incandescent bulb. My parents had a Volkswagen Passat from the 1980s (?) where the usually blue indicator light for full beam was a green LED, since blue ones were not invented back then.
That one was indeed disturbing.
The more popular photos of the Hollywood sign are taken from an angle where you don’t see the house in the background:
what are yall doing with your time?
We use our time more efficiently. Since you can stream everything from the internet, you don’t need to work your schedule according to the time, a show on TV starts. You don’t need to be at home at 7 because a new episode ist airing. With streaming you can decide on when you want to watch something.
Another benefit of not having (classic) TV is, that you barely see any commercials or ads (given you use an adblocker). When I have the chance to watch TV (when staying in hotels or visiting friends wo have TV) I’m astonished how many ads (even in the TV menu) and commercials get thrown down our throats. It’s like a stream of ads interrupted with shows.
That is a true statement. You can’t have both securtiy and wireless (convenience).
Every wirelessly transmitted signal, whether it is your network signal or bluetooth, can be intercepted from afar. It is even possible to encrypt the accoustic signal emitted from a needle printer and determine what has been printed because every letter/word emits a specific sound pattern. Sound travels wirelessly. This link from 2009 refers to that. Unfortenately it is written in German and I didn’t find anything in English, but you could translate it.
Edit: typos 2 nd Edit: Addition: Needle printers are still in use - at least in Germany - for printing prescriptions at doctor’s offices, among other things. The paper used for that provides a (physical) carbon copy.
