[badpun]

His point isn't that web development is or will be so easy that it will be easy to hire for and thus not in demand. His point is that, most of people who work on "web" code do pointless busywork or just don't work very hard. He believes that this situation will fix itself up eventually, when economics of this amount of waste will become untenable (e.g. when big tech will stop making easy money and will have to actually look at costs).
