By analogy, bringing all the printed books or hard drives you want into a chess match might help you with the opening, but not the rest of the game. These days there are chess engines, but before that, cheating required a human accomplice who was a good player, who knew what was on your board and could tell you the right move. My old club had an incident of a guy doing that using hand signals.
Now they won't let you bring any devices at all into chess tournaments, even mechanical wristwatches. A pity. Garry Kasparov famously used to fidget with his watch while playing. You could tell how good his game was by noticing whether the watch was on his wrist or on the table.
Perhaps the medical field is radically different - but I'd wager there's a whole lot of benefit that's been delivered to healthcare by giving doctors access to the internet so they don't need to focus so much of their time on trying to recall vague facts from twenty years prior in school and residencies.
