"My emergency response plan is there will always be a trained employee." is exactly as stupid as "My emergency response plan is there will never be an emergency."
How about a fire extinguisher store?
That’s very different to it actually complying with code however. And to your second example, if I was physically attending WWDC back when they did they keynotes, I’d much rather seeing illuminated exit signs than having them (illegally) turn them off in case of a fire.
Much of building codes is either outdated, no longer the most effective way to achieve something, etc. But these building codes are written in blood. It’s why we have them.
When I can see the extinguishers in the store, that's when I'll know Apple has finally gone downhill. If you're reading this Ternus, don't stop fighting.
