Agreed. Comparing UI responsiveness to yesteryear can be an interesting case study - examining precisely why things feel slower, to see whether they can be made better - but more often than not the answer is, "because we traded a bit of efficiency for an enormous wealth of usability, and iterability, and compatibility, that people never could have dreamed of back then". Rants like this post are willfully ignorant of the benefits that a technological shift can have for millions of actual humans, simply because it offends the author's personal sensibilities.
