Age has an effect, no matter if it's software or electronics. These types learned their trade once, some decades ago, and keep driving like that.

If you want old dogs to learn new tricks, teach them. No company has the money to spend nor the inclination to even suggest education to their workers. Companies usually consider that a waste of time and money. I don't know why. Probably because "investing" in your work force is considered stupid because they'll fire you the moment a quarterly earnings call looks less than stellar.
