I understand the point that PG is making here. But I think DHH might argue that it's possible to create a business that doesn't require an unreasonable amount of work and attention. The work could even be enjoyable and interesting long term and business could still manage to be a success.

Edit: I guess 37 signals is a good case study of this. They work 4 days a week and have had tremendous success. I have 0 experience running a real "business", but I have a hunch that you could build a successful one that doesn't require the amount of attention and work that PG is talking about.
