We have seen a lot of discussions on HN regarding ageism in engineering, and the paths for an engineer are more or less visible for me.
What happens to ageing / older designers? What is their path if not for an inevitable pivot to management / product management?
"Nobody knows you are a dog on the internet" Ditto being aged ~ https://en.wikipedia.org/wiki/On_the_Internet,_nobody_knows_...
Most of the technologies I play with - HTML5, webGL, Three.js etc - did not exist ten years ago. So it's a level playing field.
There's more open source stuff on GitHub that needs help and mentoring than you can shake a keyboard, er, stick at.
My digital afterlife is destined to be a thought-leader for generations to come. Fingers crossed.
As I started to understand that I am a designer, I came to realize that my own life is open to being designed. Day in and day out.
It turns out that that my design of my own life is one of my better efforts. ;-)
