I would agree.  For most things, I don&#x27;t find it very useful.  Maybe if you&#x27;re trying to learn how to use a tool, it can be worth sitting in, but for the plain mechanical tasks of coding, it&#x27;s a waste of at least one person&#x27;s time.  If you&#x27;re debugging something, you have to work at quarter speed or less - worse, if you&#x27;ve actually invested the effort to learn how to use your tools efficiently - as you&#x27;ll be bouncing around too fast for anybody without a telepathic link to keep up with.<p>Bull sessions waiting for those slow-as-death Keurig machines everybody has replaced their good old drip pots with to finish making a tiny cup of coffee are just as good a use of your time, really.
