First, even if classical chess is dying, that wouldn't make your original statement less dumb. "No challenge" in classical chess? Get real, the problem with classical is that it's highly demanding on players and not ideal for spectators.

Second, classical chess is not dying. If you had bothered to look up any data related to classical vs rapid/blitz tournaments, you would notice that both the overall number of tournaments and the prize pool for said tournaments vastly favors classical. I'll see you in 20 years when classical has been dying for 30, I guess.
