I missed this post by Anders Fogh a couple of days ago, on the academic work that has lead up to #Meltdown / #Spectre: https://cyber.wtf/2018/01/05/behind-the-scene-of-a-bug-collision/
"Well, CPU research is much like drawing a map of an uncharted world. Researchers start from known research and proceed into the unknown, and if they find something, they document it and add it to the map. This essentially means that the frontier looks very similar to everybody leading people into the same paths."
Don't need no conspiracy.
