If I can add my interpretation of his comment:
Consider which language is sold to people-off-the-street as "How to Program!" it's python. Most of these people do not enjoy the cognitive effort, detailed typing and symbolic work, algorithmic thinking, architectural thinking, linguistic thinking that is "programming". At best, the enjoy the end result, but not the process.
Python taught in this way at least, fools people into thinking that programming is about something far simpler and more toylike than it is. Many "hard" disciplines do this: sell children and lay people on toy experiments that momentarily captive but have no relationship to what a practitioner of that discipline does.
The older system of recruitment would be to polarized hard, ie., to throw people in at the deep-end to scare off all the people who would waste time/resources training. Who remained really wanted to do that thing (eg. physics, programming, ...).
Today we're doing something perhaps vaguely immoral: selling people on a career that has no relationship to the sales pitch.
