Thanks for the interesting article on simulations. I have used simulations in my job for years, but put your trust in them? As a systems engineer, we have analysts who very much desire that their model and their advice be used, but we never do until the model is "verified". Recently a model of a pressure vessel exploding turned out to be about a factor of two too low in energy. when we actually tested it, we blew the lab setting apart. So much for models.
I have had a lot of experience with ISPICE models too, it almost seems that anyone can become an electrical engineer these days. But you are right to build and test the actual circuit.
I have worked with integrated circuit designers who constantly have simulations show the silicon will work, only to have the actual first cut devices fail completely.
You would not torpedo a thriving economy based on these things. Worse yet, to get where global warming alarmists say we need to be takes about 5 to 6 Kyoto's until you are not burning much of anything at all. I guarantee the technology is not there yet.
