Right, imagine say a civil engineer building a bridge saying 'I won't bother working out the actual stresses on the trusses, I'll just estimate them from an earlier job' because it's boring--unfortunately much of good engineering is very tedious and boring, the hard slog comes with the territory.
BTW, the reason I said I'd likely not live to see software development become a profession is because the same sentiments as this blog were echoed in this Scientific American article some 27 years ago and precious little has changed for the better since then:

I think the italicized heading on page 87 sums the matter up beautifully.
