Re: So... is he an engineer?
"So you can be "SonOfRojBlake, Chemical Engineer, CEng MIChemE". Doesn't mean someone else can't be "JoeBloggs, Chemical Engineer"."
Indeed. That was my point - the term "engineer" has been devalued in our culture, in a way that, for instance, "doctor" has not. See Ben Goldacre's joke about "Gillian McKeith, or to give her her full, medical title - Gillian McKeith". Society takes a dim view of charlatans trying to pass off mail-away PhDs from non-accredited institutions as being in some way equivalent to proper doctorates, or Bod forbid actual medical qualifications. Call yourself a "dietician" in the UK without the proper quals and you can expect a swift collar-feel from the authorities (which is why the aforementioned GK and other charlatans bandy about the meaningless and unprotected "nutritionist").
But any yahoo with a spanner can call themselves an "engineer".
