He's right, the mechanical losses induced by a supercharger (especially roots type) are quite significant. Turbos on the other hand use waste energy in the exhaust, and whoever said it's the piston forcing the exhaust out of the engine and driving the turbine obviously doesn't understand how much pressure is in the cylinder when the exhaust valve opens. An internal combustion engine only uses about a third of the available energy produced by combustion, where do you suppose the rest of it goes? Installing a turbine in the exhaust is a good way to make use of some of that energy, which is why turbos have become so popular in recent decades. Not just in cars either, they're very common in aircraft engines and large diesels as well.
Having said that, turbos do have a disadvantage compared to superchargers - it's not possible to make use of exhaust scavenging with the turbine in the way. However, this is a pretty small price to pay compared to driving a supercharger off the crank.
