In some ways developing and working with a high level but less efficient language for velocity is actually a vast improvement, imo.

Take node.js for example, devs can just sling code out as fast as they can and shit gets done. Then the node.js core devs can optimise certain paths/features after the fact to negate many of the efficiency problems.

However it does annoy me that what this has meant is that many of my colleagues don't know anything about memory management, debugging, or any other more traditional concepts, so we see bloat & OOMs over time that need to be resolved.
