It's not that things get more expensive as they get smaller. As long as you're within reasonable tolerances it can be more cost effective. There is very little reason in a consumer-grade product, especially a devboard, to push any major fabs' tolerances. SMD components are grain-sized and you can make traces pretty thin.
For example, this project is a 2-layer PCB. Those are bog standard. With this small of a footprint it can be printed on a single surface and cut out. The schematic they posted keeps everything on a single surface for print. This is also an operation any fab can easily perform. If you order from China, even cheaper (even accounting for duty cost + S&H).
I'd be more concerned about the MCU and the components rather than the cost of a custom PCB.
A subtle tell for generated text is just how damn flat it is to read. Not that technical documentation require some form of grand prose, but how unspecific the text can truly get. Reading a high school persuasive essay can have more detail, and those are often just written for a grade.
I can understand someone needing help with writing but getting an agent to do the job for you feels like a personal defeat.
I've used this site for years, I originally found it off their subreddit. When they finally moved to a dedicated site it really improved the whole user experience from whatever reddit CSS was doing.
The admins keep it consistently updated and remove problem sources on a regular basis.
Yet at the same time "towards" does not equate to "nearing". Relative terms for relative statements. Until there's a light at the end of the tunnel, we don't know how far we've got.
I think part of this is due to the AI craze no longer being in the wildest west possible. Investors, or at least heads of companies believe in this as a viable economic engine so they are properly investing in what's there. Or at least, the hype hasn't slapped them in the face just yet.
