Future perfect? [Technology Forecasts]

The world future society estimates that worldwide average lifespan will increase by one year per year by 2025, and this is echoed by a variety of sources. It is good news from one point of view, but you may immediately recognise that this means major problems for pensions we will have to work longer, if we live longer. At least, that is the conventional wisdom, but it takes no account of the increasing productivity of robots and Al, which may be able to increase wealth faster than we spend it, so actually it is entirely possible that we may need to work less, even if we live longer.
