Current Stack:
Gene Mosher’s passion and vision has overseen the development, management, and maintenance of ViewTouch code across six decades, spanning a wide array of computers and point of sale equipment. Gene owns the ViewTouch copyright and remains active in ViewTouch in 2025. A personal note to everyone from Gene: I am getting on in years and everyone has always wanted me to tell them what will happen to ViewTouch if/when something happens to me. In 2025 I can reassure that I will be participating in the development of ViewTouch until my last breath, which could easily be 2050 (I’ll be 101 then), and with Ariel, who is about half a century younger than I am, being awarded co-ownership of the ViewTouch code and documentation at ViewTouch/GitHub, nothing bad can happen, is going to happen, to ViewTouch. I myself used to wonder about the future of ViewTouch, but I no longer do wonder about the future of ViewTouch. It’s going to be alive, healthy, vibrant and dynamic for a long, long time. A new chapter has been opened for ViewTouch in 2025 and I could not be happier about it. Anyone can be a part of the future of ViewTouch - I welcome all who will join us.
