I can also quote about 5 companies using Common Lisp in production, and there are enough paying customers to keep Allegro Common Lisp and Lispworks in business, yet that doesn't mean we are going back to the same amount of market presence as before the AI Winter event.
no that doesn't mean we are going back to the same market presence, indeed. Do we have or will we have a useful-enough market presence?
Here are some more companies: https://github.com/azzamsa/awesome-lisp-companies/ (only the ones we know about)
Now compare that list to the amount of companies using the top languages listed here,

Hence my niche remark, naturally there are a few using it, otherwise Allegro and Lispworks would have filled for bankruptcy already.
