Cookbooks have their place, formal and independent study have their place, experience has its place, and hands-on labs have their place. The problem with cookbooks is they may engender more superstitious behavior than a well-thought-out lab. There is also value to having multiple human brains communicating in a lab. The upside of cookbooks is you can get things done cheap and quick, as you pointed out. They sure don't age well for what we do.

Also, people learn in different ways, different work environments have different requirements. What applies to all is a good understanding of fundamentals combined with making things work well. Doing incantations in a GUI without asking "why?" is non-learning.
