The fact is that automation is fundamentally changing the economy and is going to make vast swathes of the population not only unemployed - but unemployable. Bots have already taken up huge amounts of stockbroking (which overwhelmingly happens between computers now), legal work, retail, data entry, warehouse work and manufacturing. It is by no means unusual now for a factory to operate with about 15 people supervising the work of machines. They're going to come for plenty more areas of the jobs market in the near future. This isn't speculation - it is already happening right now. The only question is how quickly.

Fundamentally, the next generation are not likely to live in an economy where it is possible for everyone to work. With very very few exceptions - even people who are highly educated, highly talented, or highly driven are going to be confronted with the fact that (by no fault of their own) there is no space for them in the jobs market.
Unless you want massive, unprecedented social deprivation and serious unrest, the economy is going to need to move away from a model where everyone is expected to work and produce wealth.
