Re: real challenges still facing human civilisation – regulatory compliance.
Called out of retirement, to fix a technical problem in a product, I told my manager that the problem wasn't technical, but structural.
When there are several competing managers telling one engineer to do three different things before the next day's conference call; when it will take three days to assemble the test equipment, and when they will have changed their minds by the next day anyway; that's not technical at all!
As the outside expert, I was listened to somewhat more readily than I would have been were I still on the payroll; I told them the objective was to put equipment in the customer's hands and what they kindly let the engineer do that.
They've yet to call me back again!
