I dunno if it's necessarily "the end" of his golfing career...
Ben Hogan came back from worse injuries, and that was even though disadvantaged by the state of medicine back in 1949, when he went head-on into a Greyhound bus... took him four years to come back, but he did come back in a very big way.
Whether or not Woods shows the same level of physical resilience and robustness remains to be seen.
Him being able to teach and play golf with his kid again would probably be the more important thing to come from this than the PGA tour where besides the Masters 2 years ago, he is being out-Tiger'd by the younger generation. Just happens. But it also happened cause of him. Everything in the sport, money, advertising, working out/fitness, better equipment, etc. is all because of him. Thats just fact.
