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 both p2p for social media/forums that sort of thing but I’m sure there are others.
Not sure about your area but where I’m at a ton of smaller venues are using the dice.fm app for ticketing, it also allows users to follow venues/bands for upcoming shows.
Bandsintown also tracks bands on tour & could be useful though I get the feeling it’s better for tracking bigger bands/artists.
Slightly old school but also keep in mind lots of venues/promoters still have email lists you can subscribe to for news/updates.
Beyond that I still keep an eye on Facebook/Instagram for keeping track of those things (I know that’s not the answer you want sorry), a lot of times that’s what the bands/artists are actually posting to.
For new equipment you may want to make sure it is Windows 11 compatible otherwise your Windows 10 laptop only has about 2 years worth of updates left https://learn.microsoft.com/en-us/lifecycle/products/windows-10-home-and-pro
Alternatively could be good time to look into installing Linux.
Investors that factor in world markets would probably do okay as long as you’re talking just U.S. economic troubles. e.g. right now VT (total world stock ETF) is weighted 64.70% U.S. market due to market strength. So in theory if the U.S. tanked and other countries have better markets for investing then the weights would shift to the other side and maybe being closer to 30% U.S. vs rest of the world’s markets weighted towards 70%.
