I say the day Mozilla bends the knee to advertisers and do what Chrome did by phasing out ad-blockers with Firefox. That'll be the day when I look around my apartment and realize "man, I need to start getting into some hobbies now."
Realistically i dont think the internet is going anywhere. But in the future i may spend less time on it.
However some freinds have been building a meshnet (not meshtastic) thats just a bunch of house nodes. Its been fun and theres already tangable benifits:
No wierd pings from 3rd parties
We host whatever we want
We pay next to nothing
No survalance
Early internet vibes
No copyright
Its pretty much the old internet but with housevto house. Im loving it.
