Nice article. I also like reading his opinions as they are based on experience and facts .
I think that the issues of grind retention, grinding speed, getting those grinds directly into the PF are addressed partly by the HG-1 grinder. That is now quite a few years old but I thought it was one of the few designs that were really novel. They started from scratch instead of just creating "another grinder" like all the others.
But dosing to 0.1 grams and allowing for humidity will be a difficult technical problem.
PS. The comment at the bottom by Tionico is also well worth reading.
