Well, you're talking about making easy things even easier (CRUD web apps connected to DBs; the inherent complexity is low). That's very important for horizontal technology expansion, i.e. 'easy IT everywhere'. For vertical progress, i.e. making complex things possible, these micro-bottlenecks are important. These same DBs with their query processing and other domains with extremely high inherent complexity would greatly benefit from high-level languages yet still the most difficult parts have to be written in the already difficult C(++).
