They generalized across an entire group of people "engineers and tech people" all but insisting that they should value "efficiency" over "effort". I am responding to the generalization and the forced assignment of values for those people (me included) prioritizing certain values over others (I don't). In general such an attitude of "shoulds" goes hand-in-hand with a lack of respect for others expressing complexity, subtlety, nuance, and especially agency in such matters. And also encourages race-to-the-bottom behaviors not just economically but also in social dynamics. It's an antisocial attitude and especially romantic partners lose interest very quickly when people act this way.
