What if some of the things that have always been wrong in the past aren't wrong any more?
Conversely, what if some of the things that we believe to be good ideas have become bad ones in current times?
What if, maybe, some things that even failed spectacularly one or more times only failed because of when they happened, the historical environment they happened in?
What if there's a whole bunch of stuff that's always been absolutely true and generally accepted to be true for so long that nobody thinks about it any more and merely dismisses the notion out of hand?
What if mixed in with flying cats and being able to walk through walls, there's some things that actually would be good ideas now?
Maybe it's a political system or an economics system. Maybe it's technological, maybe it's sociological. Logistics...
There's a fuckload of bad ideas out there to choose from. Question is - are they still bad ideas?
