> using a keyboard like this is an expensive signal

You can get premade keyboards in this layout for about $150. The Kinesis 360 mentioned earlier in the article is $400-500.

Decide for yourself how pricey "learning these things exist" and "making a custom DIY one is in terms of both resources and time.

By "expensive signal" I mean more like "hard to fake the enthusiasm" rather than "spent a lot of money".

In terms of monetary cost, the DIY ones can be quite cheap. -- But it's still going to be more expensive & effort intensive compared to just getting a typical mechanical keyboard.
