This is a call to resource managers.
Developers and testers specialize in technical matters that are at times hard to explain to the ones outside their problem domain. To reach the highest level of expertise and to keep track of trends requires time (sometimes a lot of their own time), energy, and motivation. Undermining their motivation or underestimating the time required to build their skills will ultimately decrease the quality of your products and will cost more in the end.
Consider what you can do to support them, from pay scale jumps, learning paths, reserving time in the week for developers to read and practice new ideas, to conferences and gadgets. For example, after a pay rise, Kickstarter (https://www.kickstarter.com/) is a great place to look for motivational rewards and to stimulate the developers' creative muscle.
