The reason is that for a non-techie it's hard to distinguish between a #mockup using proper widgets and the final application, so showing up with a computer-based mockup would make it hard to grasp that spending 20 hours on the mockup didn't mean the application would be ready in 40.
It was essentially a trick to counter-act the #Pareto principle: that 20% of the work takes 80% of the effort.
Making mockups using a confabulation engine ("#AI") goes in the complete opposite direction. Good luck explaining to customers that while it looks like the application is 90% done in 10 hours, you really have more than 90% of the effort left.
