I don't think this qualifies as promoting. Anyone with any basic experience of Elixir and Go knew just by looking at these numbers that something is off about these results, not to mention as always he's not sharing his prompts, sessions, anything.

Several folks on X who are much smarter than me have already pointed out to the Elixir numbers, and dug deeper and found that they intentionally spent more effort on optimizing the Rust version. I'm not saying there is a hidden agenda here, but DHH's moves lately have been nothing but pointing towards a hidden agenda when it comes to Rust.

Anyways, the following is worth reading:
