I don't know where the whole HFT thinking came from? Renaissance wasn't known for HFT, it was known for using erstwhile new technologies such as data analysis and some machine learning to find patterns between uncorrelated data (like the weather in Paris affecting LSE trades).

I think all of those points are the same for all Quant shops. All of them are at stagnant AUMs now for a reason. I mean this article seems like even GPT-3 could have written it.
