I think you are mixing up multiple things here. Improved agriculture required fewer people to generate the same amount of food. We were lucky that industrialization happened at around the same time and could provide work for the displaced farm workers. There isn't any guarantee that some new type of labour-intensive job will be invented just at the point that AI becomes widespread. I don't see how co-operatives help if there isn't any demand for their output.
