I think the demo is cool, but the single most important question is how good it is at converting written constraints into the design.

Designing something that has the right features is easy, the hard part is creating a design that is manufacturable, fits inside the allocated space, has the desired mechanical properties (e.g. rigidity) at the desired cost (uses less material, is easy to manufacture).

As an example, parts for 3D printing have various design constraints, as you want to avoid support material and want to print the part in a certain orientation. Being able to verbally tell an AI model to incorporate these constraints would be very beneficial.

I wonder where they'd get the training data for something like that.
