I can tell you for a fact that complex machines can fail despite operating well within specified tolerances. Random failures can occur despite doing everything possible to avoid them (Yes things do just happen) hence why we have things like dual/triple redundancy on autopilots, hydraulics, electrical, pneumatics etc etc.. In reality the training and knowledge from past experiences is what enables crew to deal with faults correctly.
It sounds like the most complex machine you have had access to is the family car.
No, things don't "just happen". "Random failures" are always attributable to something. That something may be defective manufacturing, but things don't just go boom unless the foundational theory behind it is flawed. As an example, the hard drive industry makes drives with three platters. If, during testing, one or two of those platters fail, the drive is programmed not to use them and the drive is sold as a smaller size. The reason for all of that, however, is that the platter in question was flawed, not some handwavium occurrence.
As to training, you are mixing your circumstances. I completely agree with your statement about RESPONDING to a situation that has ALREADY arisen, but that has nothing to do with the current conversation which is damage happening at random from unknowable circumstances "to enhance gameplay".
Making up scenarios to justify your position, especially when they are provably wrong by going back up the thread, is a really poor way to argue. Leaving aside the DCPO statement and what it implies, my car has 17 computers in the engine compartment, computer controlled fuel injection and traction control, etc. It is not some early 20th century hand crank to start the engine piece of equipment.
As to your implication that I am just an operator, I've replaced alternators, starters, wiring harnesses, radiators and the head gasket in various vehicles.
Please note that I am mentioning specific parts, not generalizing with pseudo-technical terms like
electrical and
pneumatics which are functionally meaningless because they refer to how equipment is driven, not to equipment in their own right. Certainly, redundant systems are put into place in case of equipment failures, but that is not a valid argument for why the equipment fails.
Again, the post is arguing that random damage "because the RNG says so" should be happening in game. If component manufacturing is so routinely borked that this mechanism were to be implemented, you wouldn't have an interstellar society because routine functions such as trade and people moving wouldn't be willing to risk routine catastrophic failures.
