Firearms are inherently dangerous but our job as gun owners is to make them as safe as possible while still usable quickly if the need arises. Is it possible for a mechanical device to fail...sure or mechanics wouldn't charge people $100+ an hour to work on their cars. However, In over three decades of gun ownership I have never had a single one of my firearms spontaneously fire by itself. That being said, all of the guns I've heard about that supposedly fired by themselves were due to the owner modifying the action themselves and not knowing what they are doing...you can't fix stupid. In short, I trust my guns with my life but I would not point one at my head for two hours. Murphy has a bad way of sneaking up on you when you least expect it. As for being seated and the muzzle is pointing at someone, time for a different type of holster. IWB or OWB so unless I'm sitting like Mork (yikes...I'm getting old), it won't be pointing at anyone unless there's a reason.
