I never said basic, you added that to change the meaning to what you want it to be. CNC routers are often described as "the right tool for the job" by machinists, and they can run into the millions. These magic boxes were always designed to solve specific problems. That's the generally used English meaning of tool. In my experience, people largely object to the word tool because they don't think it sounds important enough. Too bad for those people that it fits so well.
