Personally, at the very least I'd rotate my tires. If the rear isn't in great shape I'd toss it and put a brand new one up front. No amount of pain or damaged bike parts if you crash is worth the $50 or whatever your tires cost. I'd ride that tire as a rear though, not as big a deal if you flat in the rear.
In all seriousness do you ride on asphalt? Chipseal? My front tires look like the one posted after the first 100 miles with every single new tire I have purchased and I go through at least one steer tire a year. I fear not descents >40 mph. Superficial cuts in tire tread is not a cause for concern I assure you. Rotating bike tires is just dumb to me. I wear out several rear tires a year. By the time I think a front tire is too warn it might be useful as a trainer tire but as a drive tire it would last maybe a month.
