Using tools broadly but things like torque wrenches, AC vacuum pumps, and other specialized tools have mostly been too expensive to buy. Now I can buy a cheap version and it works good enough for most cases. It is not cheaper even with buying the tools to do the work yourself.

This is happening in other areas as well. The Chinese mini excavators and mini skid steers are changing what smaller landscape companies can do. They are not as good as a Kubota but they are 1/2 the price and 80% as good.
