whether or not they are relevant is besides the point, I think author isn't saying "end 4-year colleges" but rather that we should change how skills are assessed -- so that a 4 year college isn't required ... i.e you can take a test and if you pass thats it. so college could still be a valid route of developing skills (like the ones you said) but not the only route to getting a job.
