I agree that the statement "The majority of the population can not learn to code at all" is very questionable: what is the basis of that assumption ? Are there studies that took n people from different backgrounds, completely unfamiliar with coding, and tried to teach programming over the course of several weeks/months, and found that the majority were not able to get to an acceptable level ?
