There's a lot more "economy" you can do with automation, though. Automatic switched-packet routing has enabled a lot of value-add over fully-manual postal systems, for example. There's a reason there was a big knee in the global GDP graph in the mid 1800s: industrialisation, which is too say, automation of previously manual processes. It's far from obvious to me that 100% automation that obviates any need for humans is anywhere in the foreseeable future. What it does mean is that under the current system, capital will continue to tend to concentrate in the machine-owners hands, which might result in not having enough people to sell their goods to, if the rate of wealth concentration exceeds the rate of wealth generation.
