not really. almost all technological processes have increased the quality of the service.
True, but you ignore the financialization and enshittification that typically follows the technological advances. The tech processes you cite don't inherently make money for the people who developed the technology.
Air travel is a good counterexample here: technology made airlines far more productive, but much of the gain went into lower staffing, higher throughput, and cost cutting not a better passenger experience
