Outside of the language war bubble it's really great to see a post like this. Practical concerns, reasonable advantages/disadvantages of each language, a real project dealing with real timelines. Thanks!
Was going to say the same. In the past ESR has come across as a patently arrogant gun maniac, but the first part of this post is great for all the reasons you mentioned.
(What irritated me though was the switch to first-person narrative at the end).
I'm excited to see where this goes because it could go a long way towards providing concrete data for the large "work to replace old infrastucture C code with (Rust||Go||Modern C++)" discussion that has been taking place.
More data points will help to inform discussion, or at the very least add structure to the flame wars.
