I want to know the answer to the following question:
What specifically did his son work on?
All the background I'm provided with is that "In the late 1980s, according to "Richard Feynman and the Connection Machine", Feynman played a crucial role in developing the first massively parallel computer, and in finding innovative uses for it in numerical computations, in building neural networks, as well as physical simulations using cellular automata (such as turbulent fluid flow), working with Stephen Wolfram at Caltech.". Is that enough to answer the question?
Answer: no
