Real gyro != Mems gyro.

Real gyro is REALLY rigid in space. Mems gyro isn't. It causes errors after mere minutes of integration. INS systems in planes and gyros in missiles are REAL gyros. This isn't. This is more like a better mems system.

It seems like the jury is still out. Perhaps 10,000 of them work out better than a large system. It’ll take time for a lab experiment to turn into a production system.

You’re probably right in the short term, for an arbitrarily large value of short.
