Non sequitur. Even if both are true, it doesn't follow that the reduction in population will cover the loss of jobs to automation. If you posit this, you're basically assuming that the people who remain will all be extremely skilled and talented people who'll all have jobs and not be in danger of their jobs being automated. It doesn't work that way. Much of the population, no matter how large or small, is going to be only suited for simpler jobs like truck driving where robots will be taking them over before too long. People not having enough kids isn't going to change that fact.
