I agree overall, but I don't think the basic mechanism of why we have more work than ever is "jobs finding a way." That characterizes the process as jobs self-replicating, mutating, and adapting.
It's more that improvements in information processing generally (over the long-term) raise all boats, and do not fundamentally alter capitalism's competitive essence. Increasingly complex information processing can be automated, but that just moves the competition to a different playing field (er, boat pond). Until computers can create optimal, marketable solutions to novel problems, competition will always provide jobs for humans. They will just be different jobs.
