Ackshually, AFAIK around 5% of the population are homosexual. If that is completely ignored in the graph, the actual number would be closer to 22%. It could possibly be even lower if you consider bisexuals who just not had sex with women. And if you consider that homosexuality is much more accepted these days the numbers are skewed and the percentage could be even higher among younger people.
Honestly, I'm not sure if that really applies to Germany. A lot of downtown areas are kind of dying because they don't know what to do with the space that is left empty when stores close, but it's usually not the kind of store you would consider a third place. I suppose those stores drew people into the downtown areas and then people also went to a café or something, but the cafés are still there and people still go there. I haven't heard much about closures of theatres, museums, libraries and so on. What kind of third spaces are you missing?
AI is the new CGI. Remember all the early films that used CGI? Almost unwatchably bad, at least from a visuals point of view. It might get better and then it will get cheaper and probably even worse.
Check if there's a Disorcd server for your city, you might have to check if there's a subreddit which also has a Discord server. I met so many people that way, hasn't really lead to any friendships though.
There are so many places that cost nothing or very little, especially in Germany. Don't get into the doomer mindset that is so prevalent on the internet, that tell you that it's the same suburban car infested shithole that is north america. There are so many clubs (Vereine) that struggle to find new members, but you're right that you often won't meet too many people around your age, it's mostly older people and children, but that also depends on what the club is for. Be the change you want to see in the world.

As a RADAR guy I have to say they need RADAR, but I might be biased. I suppose LIDAR would be nice too. There's something called sensor fusion where you combine the measurements of different sensors, ideally using different technologies to get better measurements.
