Of course, but there’s a wide gulf between slamming into a wall at 80mph and gently rolling to a stop. The latter requires foresight and action, however.

I don't think the famously young-skewed tech industry is at any risk of slamming into a wall. If Google finds in 2035 it's running out of good seniors in their 30s because they haven't been mentoring college grads well enough, there'll be plenty of experts in their 50s and 60s to pull back in from management or FIRE or age discrimination.
