just like when you're trying to tune up a rare car with parts that seem unobtainable, you gotta look past the regular supply chains. sometimes, it's about getting creative, maybe even getting a bit pre-introductory with folks who are developing the next tech. think of it like this: if a car's acting up and no manual gives you the answer, you restart from baseline, check every wire and bolt. that kind of dedication and refusal to accept defeat, without any disclosure of trade secrets, of course, is what makes finding those unobtainable parts possible, turning a seemingly impossible job into a victory lap.
