Quite an ignorant comment. It’s literally nothing like using a CPU to prop up an uneven table.

It’s precisely the application of quantum physics that enables current prototypes of these IMUs to achieve 1-2 orders of magnitude less position error accumulation vs. state-of-the-art gyroscopes. Think 0.1m/min vs. 10m/min.

Obviously the tube isn’t the holy grail of applications, it’s just a test bed to improve the technology. Think about why GPS is useful. Imagine that, but entirely self contained.
