I agree with you for the majority of database-retrieval-from-servers apps o= n mobile devices, but I vociferously disagree the more the app differs from= database-retrieval-from-servers: https://www.abiresearch.com/market-research/product/1006117-mobile-augmente= d-reality So unlike the augmented-reality on a cockpit, augmented-reality in consumer= mobile devices is unworthy of the grand Ada. So unlike the gyroscopes on an airplane, the gyroscopic sensors in consumer= mobile devices are unworthy of the grand Ada. So unlike the GPU physics-processor in the cockpit of an airplane, the GPU = physics-processor in consumer mobile devices are unworthy of the grand Ada. So unlike the realtime crisp low-latency relatively high-frames-per-second = images in cockpit displays, the low-latency relatively-high-frames-per-seco= nd imagery in a game or augmented reality in consumer mobile devices is unw= orthy of the grand Ada's compilation to processor-native instruction sets, = but rather mobile consumer devices should display game & augmented-reality = images should have the sluggish user experience as if they are executing on= a Commodore 64, due to HTML and Javascript implementations.
