Another perspective, wouldn’t it be reasonable to believe that the faster a technology is developed, the faster it will reach its theoretical upper limit of improvement (assuming there is one)?
To use your comparison as an example, mainframes took 40ish years to be replaced by personal computing and distributed systems. Whereas smartphones reached modern parity in 8-10 years since the original iPhone and have made more or less incremental changes since.
Granted those are hardware changes and this is software but I believe the point still stands.
