I think he's partially right, and you're also partially right.
Learning to code is an extremely high barrier to wntry, but its also highly transferable. If you can write Python, there's tons of jobs you can get writing Python, and with a little extra work, you can pretty easily transition to another language with a whole other world of opportunity.
The problem with these "visual" languages, is its a lower barrier to entry, but its still takes a detail oriented person, and ends up being very specialized, so there's less opportunity to leverage that to another job. So if you're a person than can learn a visual language effectively, you might as well go the extra 30% and learn to code in a "real" language.
