Hilbert > Turing
Descartest... In terms of general contributions, Descartes was maybe the most influential on the list. Maybe sans Newton.
Bohr would be significantly above Ramanujan
Tao over Fermi? Tao is a pop figure. Even Knuth did more than Tao.
Higgs is uninteresting as well. Probably even less so than Tao, Tao at least knows a lot about many subjects. So Higgs next to Laplace or Lagrange is odd. Tao over Laplace or Lagrange sounds silly enough.
I mean why is Tao there but not Kolmogorov? Or at least Gromov.
Since you have memes, why not add Witten?
