Quotes

• "Revamping Python for an AI World" - Because of my "Why Are There So Many Programming Languages?" post I was asked to comment on Mojo, a version of Python enhanced for AI workloads. I am not sure I have any business being quoted in the same article as Chris Lattner and Guido van Rossum, but I do think that Mojo is very interesting and it's approach of leveraging Python is smart and can help avoid the PL/1 experience of trying to come up with an entirely new language. - https://cacm.acm.org/news/revamping-python-for-an-ai-world
