I do disagree with a lot of it since I believe more in maximizing human potential through mindfulness and tuning ourselves instead of our tools.
re: “ You don’t want to be the person who thinks their problem through on a piece of paper,...” For difficult problems I think you do want to be this kind of person. Walking away from your laptop, sitting outside or anywhere relaxing with a pad of paper and a pen, and really thinking is a super power.
The author’s good advice on spending a few minutes a day learning about your IDE/tools can also be applied to the idea of sitting quietly a few times a day with paper and pen and just thinking. If you don’t have this habit, how about trying it for just ten minutes a day to see if it pays off for your work style?
