That will depend on the machines suppying what the brains need to flourish, but in that respect we are going backwards.The human brain has about 100 billion neurons so they have some way to go but I guess it wouldn't be long until humans will only live with their brain, their body discarded.
Way back in 1965 Harold Wilson as PM spoke of the impending age of leisure, where there woudn't be enough work to go round due to computing, automation and robots. So we'd have to learn to live with a lifetime of mostly leisure.
Yet here we are worldwide, 58 years later, with a much larger workforce, everyone working longer than ever, with much longer lives, ever later retirement ages, a UK government desperately trying to get everyone to work to the rising limit age and disapproving of early retirement.
What the hell happened to that promised "age of leisure"?
