Yes, but irrelevant. While these models are improving at the present rate, the manufacturer can save money at no loss of feature-bullet-point-on-website by letting you download a model after you bought the thing and running it on normal hardware.
The rate of change to the models has to be slower than the hardware roll-out to be worth a hardware solution. If "good enough" happens before then, that just means the user gets a software solution.
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.
