>Ultimately, work that’s too easy is no fun, and it’s not the basis of a rewarding career. All you’re doing is selling time, and as you get a little older you’ll come to realise that time is a non-renewable resource. There's this strange myth that white collar workers try and find meaning or reward in their work. If the stars align so that the unquenchable thirst from your brain can be satiated with white collar work…
White collar workers might not; "white collar" encompasses a broad range of employment including repetitive clerical work.
Members of a profession¹ can and often do because they are talented enough to have some level of choice in what career path they go down, giving them the opportunity to seek meaning in their work. Software development used to be a profession but today most coding jobs are merely a complicated form of clerical work that doesn't really require that much skill or education (people on HN say this all the time). So while it's not surprising to hear some people say that it's a myth, I will say that it's not a myth everywhere in the tech industry.
¹ In the specific sense of "a paid occupation, especially one that involves prolonged training and a formal qualification."
