> The moral of this story? Don't get trapped by the sunk cost fallacy. Most engineers seem to have the wrong takeaway from this post. Every abstraction goes from right to wrong eventually. The answer is not to not abstract, the answer is to ruthlessly tear down abstractions when they go from right to wrong, which people seem to have trouble doing. I think the other major problem with abstractions is that they have a cost and no one seems to like to discuss that. Even the right abstraction has a cost.
