You might be right but hard to tell without analyzing costs and benefits. Is a cutting edge model for phone stuff worth the slower performance and battery drain for example?

The rate of change by itself doesn’t tell you the whole story because of costs and diminishing returns. So what if your model is twice as good if it’s 10x the cost and it saves you 1ms? Everything else about phones reached “good enough for a phone” levels in years, and then got minimal generational improvements.
