I left my oven on and am now at work. Do I need to go home to turn it off?

I just remembered that I drunkenly attempted to make pizza bites around 2:30am last night. I put them in the oven and turned it on. I fell asleep while they were cooking. This morning, I got up and went to work.

I believe my oven is still on, trying to cook a bunch of tiny little burnt pizza bites. How critical is it that I leave work now to go home and turn off my oven? What is going to happen if I don’t?
