I'm finding this hard to relate to. Our circumstances and experiences must be pretty different. But I'm afraid to me that sentence reads a bit like "I have a lathe so I don't need a bicycle". You or I might not do bicycle jobs, or lathe jobs, but it's a bit of a stretch to imply one renders the other irrelevant.

I find it interesting that you characterise static typing as about safety. I think it's more about communication. (for me this includes "communication to myself when I wrote this seven years ago and didn't think about it since", which I appreciate may be a bit of an edge case). Tests are also a great medium of communication, but a different one - in which case the metaphor becomes swap a sonnet for a sonata? I'd like both please, but maybe not always at the same time :-D
