You were making some pretty strong statements about the usefulness of harnesses that seemed to me to be entirely detached from reality. Maybe I misunderstood you? Because I can provide evidence to correct that misconception.

Another of my projects is to incorporate Pixar's ideas from RenderMan into a 3d printer slicer. Displacement shaders, in a 3d printer, have never been done before. Would you like to see that? I had the idea 10 years ago but it was too tedious to implement. I have a working system now in just a couple weeks AGAIN.

Anyone claiming agents aren't profoundly useful is WRONG. If you disagree, please let's discuss it.
