Perhaps visiting elder-care facilities and have them hand you pictures from their youth then using AI to make videos of a younger version of them participating in events from that time period and including videos of their departed loved ones back then and aged to be with them today. It should be cost adjusted for elderly to afford and they should get at least one free short video demo. Use this hobby to perfect ones skills.

Once one is good at this assist intelligence agencies and politicians with making ultra-realistic propaganda and blackmail videos to make the public question the validity of every video they see.

Authoring your own web novel on webnovel.com or other such websites

The second you start trying to monetize your hobby, it stops being a hobby.

You’re looking for a 2nd job or a side hustle. Just call it what it is.

Self-publishing books. Low barrier to entry, high barrier to sustainable profitability.

It sounds like you have your mind set on videos (which to me is a grind rather than a hobby).

Personally, I would: make video games, 3d models, generative art, board games, short animated films, that kind of stuff.

You'll probably never make money from any of this, but you said "potentially"...

Influencer definitely doesn’t have a high entry barrier. Grab a camera, a microphone and start streaming your gameplay.

But it’s a sea of blood out there.

Btw if you like tinkering with cars, it’s a good business to offer on-site “suites” — just change tires, change battery and change oil — just do these three and a lot of people including me are going to happily offer you 80-100 CAD. If I go to a dealership, they charge me something around 250 and I need to wait for 4 hours at least, with an appointment.

You don’t need to do the more advanced work that requires heavy equipment, just do these three and maybe also change filters.

That’s not how economics work. Anything with a low barrier to entry will immediately be commoditized down to zero.

I’ve had this idea that is just too awful for me to actually do it.

Create a script that generates brainrot videos with a voice just reading popular Wikipedia pages out loud.

Find some thing you enjoy creating digitally and just do that and publish.

Straight ort is probably toughest to sell, but ... if you enjoy it, one day there might be enough fans to sign up to patreon, buy your prints, book, e.t.c.

Like, you are probably choosing the Brandon Sanderson route, "Even if I never publish any of these novels, and I will die with 20 books worth of written stories that almost nobody knows about, it was still worth it!" As late sit pterry said, "Writing is the most fun you can have by yourself." You probably won't become next Sanderson or next Weir (Martian was self-published as a web-series) ... I would think that if you find your audience, you could become someone like qntm?

Also, books that teach about stuff have easier time finding an audience.

Especially if you already have a hobby that you can write about. This is the thing, you need something you are excited about or at least persistent about doing. My partner has been training dogs for over a decade, and writing training plans is not as lucrative to have as the main income, but it scales better than training in person, right ;)

Simmilarily, you could make games, publish them on itch and probably won't become next Maddy Thorne (of Celleste fame) but you could become new Brozef (look up Felvidek, it started as his university ...thesis? I think? And now it is like a game on steam and people even bought it!)

Boardgames/tabletop can be a thing - itch can work there too, but there might be a local game jam where you could cobble something together and then somebody might print&play it?

People still like to get ~human made assets. 2d art. 3d models. I used to faf around in blender a decade ago and even I heeded the siren call of a well rigged character for 10$ :D

Yeah ... reading this after myself - you are thinking the wrong way around. You need something you are excited about or at least persistent about doing. If you have several, yeah thinking about which one is more commercially viable can be good. If you have something concrete in mind, that is like a project that is good too, but you should be honest with yourself if you really need the money, or if this is a "eh, could be nice if something comes out of it, but it was time well spent even if not"
