FORGET mobile phones and the internet. There were more radical and profound technological changes in Papua New Guinea long before anyone dreamed up those things.
I suppose the granddaddy of all technological change was the arrival of the steel axe and bush knife but, other than those, change tended to be more subtle.
In the highlands I reckon (1) umbrellas, (2) men’s jackets, and (3) can openers were at the cutting edge. So to speak.
When I arrived in Mount Hagen in the 1960s, the umbrella reigned supreme. Umbrellas came in two colours, black and blacker; the kinky coloured ones came a bit later.
