So. Endless Hunger is not an AI breaker.
The practical side of this interaction is saving four MU and being able to use a standard breaker suite but then "oh also I've got this ETR breaker I can feed my exhausted counter-based breakers and other cards to". Given how overwhelmingly powerful Endless Hunger is, the ability to use it in concert with standard breakers without having to go overboard on +MU effects is actually pretty nice. It can save you a lot of credits in the long run if the corp has enough ETR subroutines sitting around and you have a few exhausted or disposable cards, and a one-of in a Shaper deck already running Dinosaurus can be a nasty surprise if you bring it out at the right time.
It's definitely janky (Hunger is basically not going to be usable unless you have Dinosaurus available to host it on and it makes your console a huge target if the corp has ANY way to destroy it), but the raw power can allow you to do some ridiculous things especially if you deploy it late game and just devour the rest of your board for a series of game-winning accesses that were completely unfeasible before now (That's a nice Curtain Wall you have on your scoring remote there...), and the cost of inclusion isn't too high if you're already using this console for other things and you have tutors to fetch Hunger when it's actually necessary so you only need one of it.
The FUN side is having a 13-strength icebreaker that basically amounts to Dinosaurus becoming possessed by Apex and devouring puny ICE. OM NOM NOM!
