If you’re not seeing anything of concern in the SMART info then there’s little to worry about. You could install/run smartctl from the command line, or for something with a gui try gsmartcontrol / any other app that can interact with your hard drive diagnostics.

Hard drives can last a long time, as a general rule if your hard drive made it through its first 1-2 years without issue then there’s a good chance it’ll keep chugging along for years. I personally haven’t found that hard drives consistently die in 5-7 years, not too sure where you got that info from.

In any case backups are your friend, not just in case the hard drive dies but there’s always the possibility that your entire OS blows up somehow or you get a bad case of malware.

Stuff like that already exists, it just isn’t overly popular or mainstream. You don’t even need to build that on bittorrent.

Off the top of my head both https://getaether.net/ and https://retroshare.cc/ are p2p for social media/forums that sort of thing but I’m sure there are others.
