Programming, when stripped of all the circumstantial irrelevancies
is nothing more and nothing less than "very effective thinking
so as to avoid unmastered complexity, to very vigorous
separation of your many different concerns".

• Business staff tends to be optimistic about debt
• Technical staff tends to be pessimistic about debt (religious and aesthetic)

• Debt is a tool, neither inherently good nor bad

Short- vs Long-term debt

• Short: violating coding standards, "we'll write these unit tests after we ship"
