So, have we become Corner Carvers? I don't think so. Heck, I'm not even the really old guard like you and JC at least as far as Subarus go, but I have wrenched on things since the 80s..
But the WRX did not invent handling, power, tuning, etc., it only introduced a new stage for the play to be performed on and brought some new and old performers to that stage.
I would also challenge that you are not the same person. Your level of expertise and skill have grown by leaps, bounds, and an engine or three!
You are no longer the wide eyed young Noob of old days yourself. Instead, you are the seasoned veteran who must now pass on that knowledge to those who come to the mountain and prostrate themselves before you.
You must now judge who is and isn't worthy...
So you have a choice. Become the jaded noob crushing egotist that exists in some corners of the web, someone who helps lead the floundering but moderately well behaved ones to teh light, or you can take your roller bearings and go play by yourself.
Next thing you know, some new autocrosser who mounts a camera and posts some video and you will you find yourself commenting on their line, braking and hands and hoping it is received with the same positive intent that it was given with and not taken as criticism.
IMHO opinion, giving back to those who come after you is what this hobby/sport is all about.
