Everybody likes to think their job or specialization is the bottleneck.

I think the domain knowledge and scientific knowledge is more often the bottleneck than people like to admit.

Sure it doesn't take a lot of knowledge to repeat or automate what the previous generations did, but such decisions were very far from the optimum considering the actual scientific frontier.

1. I admit my job is not a good sample of 'job most mortals work' 2. I still think 'most mortals' software devs aren't Antirez, and work in industries or fields that still require a human to bridge the ambiguity gap.
