They had already plateaued in 2014/2015 with Haswell/Broadwell. They've basically been releasing that same CPU with minor tweaks to power consumption and codec support for 8 years now.

At the time, it was hard to notice, but reviews at the time absolutely noticed the minor CPU update (https://www.theverge.com/2015/4/9/8375735/apple-macbook-pro-..., search "Broadwell"). Another funny aspect of that review: it mentions out 10+ hour battery life for the MBP as a nice, but hardly astonishing spec. 9 hours 45 minutes with Chrome was the worst case. It's amazing to think how bad the 2016-2019 MBPs were in comparison, to the point where getting back to 10 hour battery is an amazing Apple Silicon feature!

I don't think my 2019 MBP has ever laster more than 3 hours on battery.

My M1 Max is amazing by comparison.
