Yeeeeah, no, that's weird. Discovery rebooting it with different people would almost certainly suck, if you just want to hang out with that sort of engineery-makery-SFXy content there's tons of ways to do it now and Savage is a successful youtuber in that space. Pair it with Imahara's hearbreaking passing and that just sounds all kinds of depressing.
I'd sure love it if Discovery wasn't actively burying the old episodes, though. That'd be nice.
