they either:

a) don't care

b) were desperate enough at the time, then, like that damn videogame, it sucked him in

it's too easy to get carried away by sheer technical complexity of optimization tasks, even if you are optimizing for bad.

They may have been extremely competent at this, but if they decided to spend years of their relatively short ephemeral life on such a useless project, perhaps they weren’t the best at the time. Perhaps they needed money and were focusing on family life, I don’t know. Who I am to judge? I’m judging though.

That is really sad.
