I think the error in your argument is to talk about the history of automation. We haven’t had automation before, we’ve had mechanisation.
Automation makes human labour redundant, not just for the jobs we do now, but for any future jobs. It’s no good saying that we’ve always created employment in the past, the past is not always a guide to the future.
That doesn’t mean that humans will have nothing to do. It’s just that it will be things that don’t show up on GDP. This is a good thing: as Kennedy said ‘GDP measures everything except that which is important “.
Anyway, I look forward to your future articles, you might even be able to convince me over.
