Very interesting article and a worthy cause.
A good first step would be to define what it means to “be in tech.” There are many jobs that fall into the tech category, (web design, research, product management, UX) but don’t require to be a computer scientist.
If we talk about Computer Science specifically, we should correct the impression that it can’t be learned after a certain age. I once contacted Professor Klawe asking if she thought that 40 was to old to get a CS degree and this is what she said:
“Of course you can learn computer science. It’s never too late. You might want to consider the Bachelor of CS degree at the University of British Columbia in Vancouver. It’s a two year program for people who already have a Bachelor’s degree in any discipline. Don’t let anyone discourage you from doing this.”
These two steps would help make the field more inclusive and less intimidating.
