Because nobody saw the massive growth coming, and now it's too late.

Programming (which is different from CS, but is often mixed) is very accessible to learn (all you need is a computer and Internet), because of which it grew very fast and got democratized very quickly.

No professional body was able to catch up to the speed of growth and breadth of penetration. Before the talent crunch hit, it was too late.

I wish I could find some relevant numbers for growth, penetration and ubiquity of programming to support this claim. But for those of us in the industry for a while now (6 years of education + 15 years of working), there is a lot of anecdotal evidence. e.g. I was booed in 1996, for choosing CS as my major. And now every Taxi company out there needs software engineers.
