I retired from managing an AI/deep learning team at Capital One a year ago. Since then I have returned to my roots: doing basic research, mostly using Common Lisp.
In the 1980s I used a hardware Lisp Machine, since then I have used excellent open source Common Lisp systems like CCL, SBCL, Armed Bear, and CLisp. Just today I gave myself a "retirement gift" of a professional license for LispWorks.
