The article discusses the idea that 'boring' tech is not old, but rather mature, meaning it behaves in predictable ways and has been well-tested and understood by others. The author argues that using mature tech can reduce the risk of unexpected behavior and edge cases. The article also touches on the idea that age is not a guarantee of maturity, and that some older technologies may still be complex and difficult to maintain. The author concludes that maturity is a better measure of a technology's value than age or novelty.
