Here's the thing: for the foreseeable future there will always be new work to do with this skillset. As one blogger put it, "we are in the business of eliminating jobs". And it will be a long time before we eliminate all automatable work, if we ever do. Even if you automate one job for yourself you could find something else with which to continue growing and challenging yourself. You could also kick back and continue to (truthfully) fulfill a transaction you've made with your employer: X compensation for doing Y work. Nothing wrong with that; you don't owe them more than that. You may be taking a risk, but that's your decision to make.
