I think he's beating up a straw man, here. > The idea that someone can produce in 1 day what another competent, hard working, similarly experienced programmer can produce in 2 weeks is silly. Over such short time scales, maybe, but the idea that someone could contribute in 1 year what another programmer wouldn't accomplish in 10 years is highly plausible, to me.
