No, you literally cannot stop people from acquiring guns in the United States, as it's baked in the Constitution. Please make arguments based in reality.
When it comes to drug abuse, harm reduction can mean providing clean needles and other supplies to the user. The person isn't going to stop just because they're denied clean supplies. In the same way that you can't stop people from acquiring guns, but you can help prevent them from purchasing guns that are fundamentally unsafe to operate.
This is really cool, and I enjoyed hearing explanations of your process and decision making in the video. It sounds like you have a lot of ideas on how to develop "personalities" for units, and that's something rarely seen in game AI, so I'm eager to see where you go with all of this!
I'm definitely an edge case for music. I've been obsessed with metal since the mid-90s, and have downloaded quite literally every release. Unfortunately, the streaming services don't seem to care much about having a complete (or even particularly good) catalog of metal, so some of my favorite bands and albums don't exist on those platforms. This is made worse due to a significant portion of metal bands being off the grid, with little-to-zero web presence outside of a Metal Archives[1] listing.
This obsession has led to developing a system for filtering releases into lists of albums that I actually enjoy, so I don't miss anything good. I download 100% of releases and throw all of them into Winamp, then play the second track -- there are a lot of atmospheric intro tracks in metal. If the first 1s doesn't grab me, I skip to about 0:30 and give it another 2-3s. If nothing grabs my attention or it's a sub-genre that I'm not interested in, the album gets removed from the playlist.
Anything remaining at the end gets a full track 2 play, and if the whole song meets my approval, I'll listen to the whole album. If the album is something I'd listen to more than a few times, it goes on the permanent playlist -- currently at ~450 albums and another ~500 random tracks.
As a 5TB MP3 hoarder myself (along with ~50GB/day of movie/TV pirating), I was curious as to how much content 30TB actually is, so I checked the average file size for my last 300 downloads of mostly 1080p shows and 2160p movies. They averaged 3GB, so that's roughly 10,000 pieces of long form video. Presuming an average bitrate of 14Mbps, 30TB is ~4,760 hours.
The average adult watches 3 hours per day. Given the OP's hobby-level interest in collecting the content, we can probably double that to 6 hours per day, which makes for 2.5 years worth of content.
Even though I'm squarely in the 6+ hour category, there are maybe 100 or so favorite movies that I've watched more than once, and once per year I'll re-watch a TV series (this year's revisit was Halt And Catch Fire). But even adding all of that together, we're talking about maybe 500 unique videos over ~20 years.
I can't wrap my head around needing to store 10,000 videos forever for the tiny chance that you might want to watch one that isn't still available through Usenet, private trackers or reasonable paid means.
