I had the distinct pleasure to make a trip with late Nobel laureate Jack Steinberger to CERN. And while he was certainly deserving all the recognition he got, he himself mentioned that giving prizes like the Nobel to individuals (and I would presume Turing is similar) becomes increasingly outdated. When Nobel conceived the prize, it was still a common thing for individual researchers to make big advances more or less in isolation. That is just not the case anymore in almost any scientific field (math might be an exception, idk). Prizes should go to research groups because most fields of science have become so complex that its very hard to get anything done as an individual researcher. The nobel peace price is regularly awarded to institutions, so it is not inconceivable.
