My own experience tells that the most effective way to persuade the boss that some approach works is to offer him 75% ready solution using it, for the boss (on average) is eventually looking for solutions not for technologies. Unfortunately such an opportunity is quite rare... In general bosses deserve to be undestood. Treat this as a producer-consumer chain. You as a developer consume technologies and produce working code. The boss consumes your outcome and produces whatever he is expected to produce to feed the next in chain consumer and so on... At some stage in project's life every new technology looks the more desireable the more it is a profitable replacement for already used ones, not just fashionable extension. So that it makes your outcome easier to consume, not just your skills alone are pumped up.
