There is little to object to in this post, but there is also little to praise. While it is an accurate description of the differences between OpenAI and Fast.ai, it doesn't make a compelling argument that Elon and friends should be spending their money elsewhere. Indeed, if the potential for neural nets to help the world is so large, research into techniques like RL are by extension even more promising, and should be funded and explored. Sure, neural nets are being applied to all sorts of new problems of the sort we are familiar with. This is a period for making incremental improvements in the paradigm. But that should not obviate or preclude research that will lead to a paradigm shift. A false dichotomy.
