Had an old phone, around when smartphones started being a thing. Emergency services was #08. And with keys locked, # 0 and 8 were the only keys that would register. Literally couldn’t have it in my pocket. Had to keep it in my bag. Probably 20 calls to emergency service before I figured out that those keys didn’t lock.
Depends on what you mean by forever. Who knows what tomorrow brings. We could be smashed back to the stone age, and effectively extinct, sometime next week.
