The discussion revolves around an experiment comparing programming languages used for software prototyping, notably Haskell, Ada, and C++. One notable finding was that a novice Haskell programmer managed to produce an efficient solution, highlighting that language productivity may not solely rely on the expertise of the programmer. Many commenters emphasized the importance of language familiarity when forming development teams, and questioned the validity of the experiment’s conclusions given the small number of submissions per language. The conversation also brought up the potential benefits of incorporating modern languages like Rust and Go into such experiments, since the industry is rapidly evolving. Additionally, sociological and psychological factors affecting the adoption of functional languages were highlighted, as well as the longevity of known programming language efficiency research in practical scenarios. Overall, there's a call for updated comparisons and a broader look at modern programming languages to gauge productivity adequately.
