I've been programming for 60 years. I started working with LLM in mid-2025 and have created a number of useful tools in my consulting business. For the programming part, and actually the planning part, I estimate that it increases my productivity by a factor of 5.

Additionally, I always am looking closely at the code and I think I am an incrementally better programmer.
