I spent time in Japan on a project with an 80 hour per person average workload. It was millions of dollars over budget and years late. Putting in the hours was cultural around not wanting to let the team down, but there was a leadership failure too. Crushing people to implement bad (or vague or undocumented) decisions made the problem go from bad to worse over time. My sense is that in tech jobs it just doesn’t scale. There are professions where it does seems to work. Banking analysts who expect to go back to school in 2 years crush themselves to get Goldman Sachs banking on the resume.
