You don't do that by disobeying your boss - you do it by quitting, finding your own clients, and saying "your competition is taking 6 hours to do this, and I can do it in a fraction of the time by using new language/feature/technology/process X", and beating your boss at his own game. If your boss isn't paying you to look at the new technology, do it on your own time and in your own projects. If you want, you can come back afterwards and say "based on my personal experience, we can save time/money by switching to X" and give them the opportunity to try it out - or to overrule you.
