Blurry photos is fine to make an stylistic choice. The 2019 movie The Lighthouse stylistically looked like a 1920s film, before modern music intentionally used bitcrushing, it used vinyl cracks, boomer shooters made in this decade intentionally look like 1990s Doom clones.
When a medium's shortcoming is patched by technology, it ultimately becomes an artifact of the era where it was accidental. Once a few years have passed, it becomes more synonymous with the era than the mistake.
It's not necessarily nostalgia, Gen Alpha and the younger half of Gen Z never grew up without smartphones, so they don't miss the era of poor film photography. Although every generation does this simulation of forgotten mistakes, it's particularly poignant now, where the high quality, perfectly lit, professional feeling photos convey something artificial, i.e. smartphone software emulating camera hardware, faces tuned with filters or outright AI generated content. Even if it's false imperfection, the alternative is false perfection.
Art using deliberate imperfections that were unavoidable in the past is romanticising something perceived as before commercialism, and that's admirable.
I finally got round to a significant upgrade to my PC last week. I've been running the same PC for 10 years, and it's really been dying. Fans and HDDs were failing, and it couldn't play new games at all.
I haven't replaced my GPU (still on a GTX 980ti) but I jumped to some decent DDR4 RAM, a better CPU, and moved into an SFF case, but I have no confidence any prices are set to stabilise, so I just gave in and built what I could.
