The main issue is that I don't really care much for old technology or anime or videogames anymore.
I used to, but now I find myself more focused on the development of tools that we have today. The only thing that might be /retro/ that I sometimes care about, is demos for old computers like the commodore, zxspectrum and amiga. But it's a veeeeery small kind of interest.
Sometimes I also had a slight interest for the PC-98, but besides Touhou it doesn't seem interesting either, it just seems like a bunch of VNs in a language I can't read, and that due to cultural differences, don't really care about
