I wouldn't worry about the effect of bootcamps and the surge of unqualified programmers. All they do is create even more demand for senior developers to manage them and clean up after their messes. I know it's ridiculous for someone half your age to give advice, but if you're worried about diminishing earning potential, ageism, and lack of respect, consider consulting. Your experience is directly valued and the earning ceiling is much much higher (if it exists at all). I know several 40+ year-old developers who have had tremendous success working as consultants and getting lots of respect from companies which otherwise exclusively employ 20-somethings.
