As a college student who followed along Berkeley's SICP lectures online in 2015 (taught by John DeNero), I am kinda confused by the Scheme v/s Python debate. Did I miss out on something having used Python in the entire first half of the course v/s say CS61A taught completely on Scheme (like when taught by Brian Harvey)?
Yes, I believe so. I think Brian Harvey puts it aptly, "The big ideas in the book — the ones that alumni in the real world tell us they’re using in their work — express themselves best in Scheme."
