I got news for you, the Chinese martial arts are still being used in competitions. They are usually referred to Sanda, Sanshou (in some parts of New York, they are even referred to as San-Duh! (TM)...
).
Also, many people in law enforcement, security industry, etc. still use TCMA techniques and training for REAL combat applications, and again, many sifus, will fight challenge matches if they are challenged!
As I explained above, the Chinese martial arts's combat effectiveness is on display for all to see. Of course, you will see better if you had practiced them yourself?
What is fact is that you are not in the TCMA community, as you do not practice authentic kung fu, so obviously your "facts" are "different" from those of us in the know.
