Ask HN: What cutting-edge technology do you use?

What technology do you use today that is far from mainstream? Think Tony Stark technology. Examples are mobile phones / internet in the 80s, metal 3D printers, quantum ML, night vision device, large language models (GPT-3) for personal communication, CRISPR, manned drones.

I run a site that gives sports betting tips. I use the text generation to automatically builds narratives for thousands of games a day. I use affiliate programs with online betting sites and pull 80k/yr just with AI text ( started 4k been doubling each year)

Or maybe this is mainstream already and i don't know.

And the tech stack includes?..

Pen and paper. ;)

Also, I have been using an agenda with on the left side the week, and on the right side notes for the last 10 years. It has a special holder for a pen, contains some information on units, UTC differences, a world map, holidays, year overview, and much more. This is very useful. At work I only have to carry around my agenda. It contains all information that you need directly in meetings. And I can take notes on the right side that I can process (digitally) when I'm back at my desk.

Fully controllable pocket computers.

Surprisingly, the tech has been there since the '90s, but never really caught up. Then it went into a weird walled garden direction with mobile phones that often work against you.

Pocket computers are still sometimes janky, like Linux phones are, but having access to all the software and permissions is an unparalleled power.
