Turing like a lot of pioneers is seriously overrated. When surrounded by low hanging fruit it’s easy to seemingly make a great deal of progress especially when your credited with formalizing existing ideas or making that one last step into usefulness.
Einstein actually pushed boundaries in a well established field which is vastly more impressive. Musk significantly pushing the boundaries in cars, rockets, computer networks, and banking is quite impressive in that context. We can quibble about PayPal, but I am being consistent in ignoring the charging network and self driving system etc as those are emerging fields. Clearly he’s not operating alone, but few people did.
Newton is perhaps the most obvious example of significant progress in independent and established fields and IMO far more impressive, but it’s really not a long list.
