Bruce Lee gave so much advice in his relatively short time as a professional martial artist and fitness instructor. Fortunately he left many notes and journals that have now been made into books, so that we know more about his training methods and philosophies.
In short: Lee is a legend, and I understand no one wants to see a legend change. But the argument that Lee would train quite differently today. Before I developed my system, Training for Warriors (TFW), I was certified in Jeet Kune Do and studied Lee's training methods extensively. I am convinced that as a result of the combination of current training methods and his progressive philosophy, he would have been even better today.
