Bobby Fischer was obsessed with chess. Modern chess players have access to a lot more information about chess; records of all of the chess tournament plays, high quality chess computers, on-line play. That doesn't mean that Booby Fischer was less obsessed than modern players.
Newton in his early years was obsessed with science. Modern scientists have access to an entire industry and government infrastructure for supporting science. That doesn't mean that modern scientists are fundamentally more obsessed about science than Newton was.
