In several other posts here, I have distinguished PysoniQ from the open source projects mentioned. It has much better ease of use and faster published metrics than the other projects mentioned. The faster metrics should not be surprising when technologies like LLVM are cut out of the loop and you translate Python directly to assembly. The translate "directly" is critical for performance.
When you say, "But it's also not like there aren't already 5 or more open source projects that do a similar thing better already" can you be specific and provide examples of how they are better?
