What you call a "Middle Man" is also known as a "Market Maker" or a "Liquidity Provider". He takes on the risk of connecting supply and demand in order to profit from the bid/ask spread.

The "Middle Man" has been replaced with technology because it's more efficient and enables more liquidity than an actual man or a network of men could.
