The kind of black-and-white thinking that programmers are understandably prone to often leads to them denying the existence of their own blind spots.
A lot of 'coder-first' programmers might see themselves at a disadvantage in job prospects in the future, especially compared to a math, stats, engineering, chemistry, physics, biology, history, geography, accounting, business, or any other majors really, who not only know how to code well enough for most jobs, but most importantly, how to apply their knowledge of programming to unique problems in their complex field.
A lot of other fields do a great job at training you to be an independent investigator first and foremost, specific knowledge second. This is one of the shortcomings mentioned to me from my friends who graduated with CS degrees: a lack of solid reinforcement on hypothesis driven analytical thinking especially, and too much emphasis on algorithms they never used again once they passed that particular exam.
A hiring manager therefore might take the polymath who knows programming over one of the thousands of applications they get every year from dime a dozen computer science graduates with great grades from a big school and some random capstone project on their github.
Sadly not my experience in the UK - it's all top grades in maths/physics/comp sci, x years experience on x ridiculously long and highly specific list of technical skills.
Plenty of techies can (and do) do it all. The opposite - not so much.
I'm not sure how you don't recognize that that is EXACTLY the point being made: tech people think that the work of non-tech people is less important, less critical, and more easily done then their work. And that their work is special in that non-tech people are not capable of taking up a role at a keyboard and doing a good job.
I'm having a difficult time understanding how your statements can be interpreted any other way.
I told myself for years that it would be "easy" to quit smoking, and in the end, it actually was. The hard part is that it just plain isn't fun. In a funny way, quitting smoking gave me more empathy for nontechnical work.
As for quitting smoking our experience is different there too. But glad we both quit. :)
And yeah, I think for the most part people learn to find some kind of joy or at least entertainment in what they do for work. Or they learn to be miserable sustainably.
