Great presentation as usual. One fundamental tension I see in much of the work he does is between purpose-built and general-purpose tooling and environments.

The challenge in both the maker space as well as much of the visual learning and programming material he has done previously is that each of them is incredibly time consuming to adapt to each new different project. In the real world even similar tasks within projects in the same domain often have enough subtle differences that re-use is not possible or very costly.

That isn't to say these are insurmountable but maybe much of the focus needs to be on meta-tooling that can accelerate the work of experts to build these purpose-built environments (as opposed to making generic tooling).

Inspiring stuff.
