Yes the reality in this world is slowly being replaced by 'artist impresions' and 'simulations'. Nobody notices, the next mars rovers will actually be just some simulation running on google's computers. And NASA will still get 100 billion for that mission.

This sort of thing is standard in press-release science. The application sounds silly to me. John

T(on) may be quick and strong but t(off) usually seems to be slow and sometimes troubled. Maybe there is some quench circuitry involved that they are not talking about. Or maybe i, yet again, do not quite know what i am about, Dr. Hobbs? |
