Caves haven't changed since the 70's and the required training and experience to safely explore them hasn't decreased due to anything but pompous bluff and money. We quite clearly see the damage the reduction in dive training in general has done to the sport. While there are always exceptions most folks aren't going to become quality divers if the standards continue to deteriorate. If trying to cram more training into less time to satisfy the instant gratification generations is your idea of progress have at it. I'm already certified.
