Which is a reasonable handwave until you start asking about the physical damage that the bullets do to [EDIT] hosts and ignore the mayhem involving explosives, fires, etc.

It doesn't especially bother me though. We know that TV and movies generally have a convention that trauma that would put someone in the ICU in the real world is brushed off as a flesh wound. And I'll accept technobabble about the bullets. I'm also happy to accept that maybe Westworld takes place in a culture where theme park risks on par with base jumping are considered fine and proper.
