Ask HN: Any interesting niche hobbies?

I don't think chess engines are a solved problem for some use cases. Yes you can make something strong, maybe even the strongest, but can you create a chess engine perfectly tuned to actually teaching a player? Instead of superhuman perfect lines and inscrutable long-horizon strategy, can you teach nearly optimal human play in a way that's actionable, modular and memorable? Can you improve on tournament prep for players against particular opponents or within a particular metagame?

Also, obviously it's your life, and we're here on Earth to fart around, but I have spent a good portion of my life dipping into one hobby after another, as my dad did before me, so I'm half speaking to myself when I ask this: why do you think you can't meaningfully contribute to any of these realms, even now? To me that sounds like some deep seated fear or doubt, some aversion to competition, some overriding bitterness. I'm slightly worried you'll just be back here in another couple of years trying to find another new hobby, unsullied by the efforts and achievements of others. You won't find that! I would actually suggest a particularly expensive hobby: going to therapy. Try that, and learn that you're already enough, and if your contributions are meaningful to you, that's all that matters. Happy to be way off the mark here though.

Fast fashion forces you to dress for the masses. Loose shirts, baggy pants and shallow pockets is not fashion, its cost optimisation for brands.

I didn't want to dress up like a boy. Me and my friend were in Paris when we got inspired by the floor(fashion_sense). I was already working on my clothing, but that day we promised each other that we will not be underdressed anymore.

He opted for off-the-shelf formal clothing: high quality shirts, and pants. I went all in.

First I found markets that sell cheap fabrics, so I can experiment. I travel a lot, so my clothing had to be designed for all weathers. I'm Indian (Bharat), but look racially ambiguous, so I also wanted my clothing to reflect my roots and culture, yet be modern enough for any room in the world.

I run a company, and write code, so comfort was paramount. But I also had meetings or presentations so I wanted to be presentable.

Started with pants, because I thought pants are easy to optimise, and I just need a black, gray and dark blue one. Over 5 iterations, I reached a design with elastic straps on the side (because when I eat food, my tummy bloats a little and its uncomfortable to sit down), and loose on the thighs. Imagine pyjamas, that look like pants.

Then next step was to experiment with jackets and shirts. I played with fabric, patterns, and finish (zippers, titch buttons, different cuff lengths and styles, different collars).

My friends started noticing, and I also consulted some clients. Then I gave a talk about it. This is one of my skills that I discovered by first principles. The best part is that I met my girlfriend because she noticed my aesthetics, and she told me that she makes her own clothes too.

I got into improv theatre. There are groups in every city, at least here in the EU. It is both fun and developing creativity, alertness, etc.

I use Blood on the Clocktower to do this, it's a social deduction game (that's just not randomly accusing each other) so it gets everyone talking easily

That's pretty neat, and we should talk. In my household we are currently producing about 75% of our clothing, mostly out of a desire to avoid using fabrics that generate a lot of microplastic waste + observing that newer clothes/fabrics wear out quickly.
