Ironically, because I'm ancient and appear soberly astute, I'm continually being asked to address corporations eager to learn about my nonexistent business acumen.
I think they're confusing me with Owen Glenn.
Skimming his book recently, the only thing I noted us having in common is that he doesn't favour boards of directors, echoing my philosophy: "If you want to get something done, form a committee of one."
It must've been fun working for Glenn. I understand from past employees that his idea of social interaction was to take his staff off on rip-roaring trips to Las Vegas to "unwind". By contrast, this makes my idea of offering staff an afternoon outing to Waiheke seem slightly feeble.
So, what's changed in 50 years? Well, in my areas of speciality - corporate offices - the big shrink is on. Thanks to computers, nobody needs desks or space the size of an aircraft carrier anymore.
Oddly, we're now in the era of long-bench desking again, similar to the typing pools of the 1920s.
What's around the corner? Reviewing the latest ergonomic research suggests we'll all be returning to bar-height desks, complete with high stools allowing employees - especially those slaving in call centres - the opportunity to stand or sit while working.
This is to counter the fast-growing risk of thrombosis, apparently aggravated through spending long periods sitting at a standard-height desk staring at computer screens.
So, if you want to be on the leading edge of tomorrow's design thinking, go and buy yourself one of those antique Dickensian desks favoured by Ebenezer Scrooge.
