ShiVa (at least the Advanced version) also does this "changing values on the fly" trick. Not an easy feature to implement, no nudge, no wink.
This guy in the video... nice. But. When he talks about accidental discoveries many people might miss that he was doing something meaningful, going from point A to point B in development and he knew both what he was doing and where he was going. This trick didn't remove the need to code. This trick, as demonstrated, can help coders under certain circumstances. But it's not a panacea and can't be intended to remove the need of any coding by giving no-coders means to fiddle with code written by others.
Chaos. Mayhem. Destruction. I'd love to see the results untrained of people dealing with such a feature like they would press the "Make Me A Cool Game" button. Beautiful!
And, well, I'm just one of those who "just play computer well in their heads".
Dismissing years of training and conditioning, "just" because, wasn't so nice.
Pays the bills, gets jobs done.
Gets people to call you a Mentat.
Others "just" make nice speeches.
