Even the simple act of connecting to an external display (2560×1440, mind you) gets my machine an extra 20° warmer. These could be platform-specific issues (i.e. Apple hasn't done a good job with thermal management, GPU drivers, or both), but something has gone awry.
After fast internal SSDs became mainstream around 2015, that was the last major boost I've seen to the overall computing experience. For example, open/save dialog boxes loaded much faster, and other common actions were a lot zippier. Apart from that, there's been no perceptible improvement whatsoever in terms of "daily computing". My CPU and RAM resources have increased dramatically as I've upgraded laptops over the years, but I can hear my fans more often than before doing the same exact workflows.
I'm just as shocked as you and want answers.
