I think the article contains good advice for solving tactics puzzles that are meant to be about calculation.
I still like training exercises such as puzzle racer because those can help you to become more familiar with tactical patterns and improve the speed of candidate move generation for forcing moves. It's true they invite shallow thinking, but if the thinking becomes too shallow it will even begin to show in the score of these puzzles.
Doing them for calculation training would be harmful for sure though.
