I think the difficulty in seeing how this time really is different is that increasing technology is exponential at replacing human labor. But exponential growth is extremely unintuitive. It initially looks linear, and this approximately linear phase can last an arbitrary amount of time. But eventually, a wall is hit and seemingly overnight the explosion is unstoppable. I feel we've been in the approximately linear phase all this time which is why we have so many naysayers saying this time isn't any different. We'll never have the political will to make changes until a third of the country is unemployable.
