Maybe this language has a bad name but I can not find anything about it on HN.

I'm not a professional programmer, but one of the best things about Common Lisp is that you can find code that was written decades ago and it still works without any changes. You may say that longevity is just a coincidence, but I believe that this is one of the proofs of the enormous power of this way of writing code.
I would like to have a PC/Smartphone without having to change devices for the rest of my life (not expected to see that much progress in hardware anyway) and be able to install any old or new app. What a pity that the industry has chosen the method of planned obsolescence in both hardware and software.
