How would Sherlock not work in modern day? Ever heard of Batman.... ?

So much information is readily available today that a modern day Sherlock would be even more of a genius in terms of knowledge base.

And I assume the choice of them using their first names has to do with it being the 21st century, though admittedly pointless since people might still call close friends by their last name for various reasons, so I dunno.
