If you're building something that already reasonably exists, you better be sure you can do it 3x better (for some economic metric of better, e.g. cheaper, bringing in more revenue). If not, you're wasting your money in a different way, by not focusing on the things that really bring in revenue or by paying salary to people to maintain it.
