It failed before because system resources and horsepower were too low to make it work smoothly (&, let's be honest, because there were often poor UI choices going hand-in-hand with poor speed/smoothness). Plenty of ideas resurface, not because they were bad & people think they just might work, but because they weren't practical when they came up. There are plenty of faded-away applications & forgotten old OSes with ideas way ahead of the curve, needed speed and/or memory, & were laughed at & called stupid because of system limitations that will show up again in our systems, someday.
