Why do a decoction mash?

Transcript
At the meeting of the Salads, the local homebrew club, a homebrewer asks for opinions on his beer.
Home brewer: What do you think of my Czech pils?
Other homebrewers: Mhm, great stuff!
Nice bready aroma.
Awesome!
Nailed it!
Love the caramel flavor!
Home brewer: Thanks! I did a decoction mash.
Other homebrewers: You don't really need decoctions.
Today's malts are so well modified.
Just add caramel malts.
Really not worth it.
Archaic.
Max: Wow. We need to do that deco mash thing, too!
Paul: Why? You heard them. Not needed anymore.
Max: You saw them. You don't do that deco thing for the taste, you do it to impress homebrewers!
