Altshuller's law of uneven development of parts of technical system reads as follows :
From this some people make a conclusion that if all parts of a technical system are developed evenly, then there will be no contradictions and problems. This is a logical fallacy. If A implies B it does not mean that not-A implies not-B. Indeed, suppose that A is false and B is true. Then A implies B because truth can be derived from false assumptions. However, in this case not-A is true and not-B is false, and lie cannot be derived from truth.
Thus, even development of various parts of technical systems can give rise to contradictions and problems to the same degree as their uneven development ! This Altshuller's law is absolutely useless as a tool because does not give any indication as to how various parts of a system have to be developed so that contradictions and problems would not arise.
I would suggest that they have to be developed harmoniously, which is also not specific, but at least less misleading.
