According to Scott Sumner:
I thought I'd make a list of things I have now that I or my family didn't have 50 years ago and include the approximate date I or we acquired them:
My grandma was born in 1890 into a middle class family in small town Wisconsin. Her home probably lacked indoor plumbing, most home appliances, electric lights, telephone, TV, radio, car, etc., etc. Slightly improved from life in ancient Rome. She lived to see jet air travel, computers, atomic bombs, antibiotics, and died the week they landed on the moon.
I was born in a world of indoor plumbing, atomic bombs, jet air travel, home appliances, computers, cars, telephones, TV, radio, antibiotics. I'll turn 60 this year, and live in a world of indoor plumbing, atomic bombs, jet air travel, home appliances, computers, cars telephones, TV, radio, antibiotics, plus the internet and cell phones. Yeah, I'd say change is slowing down, really fast.

Progress before and after 1919 or 1972
According to H. G. Wells (writing on improvements in the process of scholarly research between the time of the Library of Alexandria and 1919):
It is curious to note how slowly the mechanism of the intellectual life improves. Contrast the ordinary library facilities of a middle-class English home, such as the present writer is now working in, with the inconveniences and deficiencies of the equipment of an Alexandrian writer, and one realizes the enormous waste of time, physical exertion, and attention that went on through all the centuries during which that library flourished. Before the present writer lie half a dozen books, and there are good indices to three of them. He can pick up any one of these six books, refer quickly to a statement, verify a quotation, and go on writing. Contrast with that the tedious unfolding of a rolled manuscript. Close at hand are two encyclopedias, a dictionary, an atlas of the world, a biographical dictionary, and other books of reference. They have no marginal indices, it is true; but that perhaps is asking for too much at present. There were no such resources in the world in 300 B.C. Alexandria had still to produce the first grammar and the first dictionary. This present book is being written in manuscript; it is then taken by a typist and typewritten very accurately. It can then, with the utmost convenience, be read over, corrected amply, rearranged freely, retyped, and recorrected. The Alexandrian author had to dictate or recopy every word he wrote. Before he could turn back to what he had written previously, he had to dry his last words by waving them in the air or pouring sand over them; he had not even blotting paper. Whatever an author wrote had to be recopied again and again before it could reach any considerable circle of readers, and every copyist introduced some new error. Whenever a need for maps or diagrams arose, there were fresh difficulties. Such a science as anatomy, for example, depending as it does upon accurate drawing, must have been enormously hampered by the natural limitations of the copyist. The transmission of geographical fact again must have been almost incredibly tedious. No doubt a day will come when a private library and writing-desk of the year A.D. 1919 will seem quaintly clumsy and difficult; but, measured by the standards of Alexandria, they are astonishingly quick, efficient, and economical of nervous and mental energy.I read the above passage in the early 1970s. At the time, there had been little change since 1919. The progress since the early 1970s has been much greater.
