Yet I constantly see people ruing how so many things are clunky and unusable because they're "designed by engineers."
Really, it doesn't matter if a designer, engineer, middle manager or janitor design something. What matters is the design. "Artistes" are responsible for millions of crap works that can barely sell at a garage sale or flea markets for every work worthy of being hung in a museum. The best user interface designers I've worked with have always been tweeners who fall between engineer and designer... and "artiste" universally never applies.
What is going on right now is silly - we're designing user interfaces based on users being inexperienced and stupid, which is now an edge case. Reality is that computers have been in common use for 25 years. That means the vast majority of users have at least 3-5 years of computer use experience. Today's users are smarter, are comfortable with mobile, desktop/laptop and all kinds of other user interfaces (i.e. ATMs, car dashboards, DVD Players, video games, etc). We should be taking advantage of this instead of designing for the 5% of users who are really confused.
The whole "dumb it down" movement is based on anecdotal evidence and reminds me of website redesigns that use a focus group instead of the last three years worth of web analytics and customer complaints. The result usually is a 10-20% drop in sales followed by rolling back to the old gui with round buttons instead of square or vice-versa.
