I don't think that's a particularly relevant metric, as we can easily restrict programming to languages like Lisp/Pascal from the 70s, and the landscape doesn't change much.
I'd also suggest that our chess bots have evolved dramatically in that time. Deep Blue works very differently than AlphaZero, for example. Deep Blue might not be suited to code generation, but AlphaCode spawned from AlphaZero.
