I recently posted about the trend of “productivity gurus and marketers” making inflated claims about how much people can learn or otherwise accomplish in a short time.
This trend is particularly common in the domain of language learning. Language-learning apps routinely make absurd promises of fluency in their marketing materials. This spreads the notion that learning a language is (or ought to be) quick and easy. If that is what people expect, they are likely to be disappointed and give up language-learning when it turns out to be neither quick nor easy.
