That&#x27;s definitely correct.<p>One related unsolved problem in that type of research is getting people to share their actual code.  Especially when multiple universities are at the bleeding edge in a field, they often publish just enough [1] to prove their point without giving everyone else the same foundation to build on <i>easily</i>.  Even in science it gets political... who knew.<p>1: i.e., just their algorithms, or their code without very useful implementation-level optimizations
