It is nonsensical as thought experiments go; we're comparing two things that can't be compared. But just for fun - if we existed in a world with no medicine and the internet, we'd be able to rediscover modern medicine extremely quickly. We might reasonably expect to get further than the current state of the art, in fact, because the initial wild west phase wouldn't be encumbered by overzealous safety regulation and we'd learn more before the legislatures of the world start shutting it down (especially since the baseline would be so horrific, they'd probably have tougher stomachs for some broken eggs while making omelettes).
We ran the reverse (medicine then internet) and it took a long time to get to the internet.
