Idk I think you’re being far too kind. I work in urban planning and the thing about the mid century groupthink is that is was so obviously doomed to fail. In fact, it’s gone far better than any planner then could have hoped! Population projections from the time expected modern populations to be far higher than they ended, and as plenty of people pointed out at the time the geometry just made no sense. Highways are too low capacity to work in urban environments. It’s absolutely fair to slam what was an obvious mistake at the time it was made.

Similarly, the seaport does not reflect modern planning best practices at all. It’s held up as a model by planners of what not to do, no hindsight needed!
