Yep; we all carry some of the dinosaur genes in us.You mean all the birds: living dinosaurs in the present?
I did not write that all programs are immortal. There are some. The information in the hardware (organism or virus) is information. It doesn't matter if it's a tomato or dinosaur organism, if it's similar or identical
In fact, we all carry much, much more ancient genes in us, originating 2-3 billions of years back - the very basics of life did not change.
Oxygen-based oxidation, iron-based oxygen transport are only few examples of immortal biological programs (immortal - for as long as life on this planet exists - which is not forever).
