This chapter mentions three times "video above". However, all the referred videos are actually below. They occur in the Sketchpad video and the mother of all demos video.
Midway through the final paragraph, in the 4th question, there is an “o” missing in “computing” right before the word “interactive“.
Unrelated, but I also noticed that the second sentence in the second paragraph is grammatically incorrect as there is no subject in the sentence syntax and the "of" should be removed due to redundancy. "Called it the “Analytical Engine”, and conceived of it as a device that would encode instructions for calculations." should be "He called it the “Analytical Engine”, and conceived it as a device that would encode instructions for calculations."
Add a table of all the important people and a one sentence description of how their contributions influenced the field of interfaces, or a visual timeline of historical moments, could be fun to have a timeline that moves through the chapter while you scroll
It isn't clear whether readers should watch the entire video, maybe link to a timestamp?
TYPO: And indeed, at the time, people were the bottleneck: if a banker wanted a list of numbers to be added, they needed TO hire a computer.”
P1 "And yet, for a medium that is invented entirely from imagination, the history of user interfaces is a reminder that the interactive world we experience today didn’t have to be."
Also, the end of this sentence is a bit ambiguous. Didn't have to be what? I had to read a couple times to understand the meaning.
P2 " He called it the “Analytical Engine”, (delete comma) and conceived of it as a device..."
P2 "And indeed, at the time, people were the bottleneck: if a banker wanted a list of numbers to be added, they needed to hire a computer..."
P2 "Baggage’s (should be Babbage) “Analytical Engine” promised to do the work..."
P2 "...was enamored by Babbage’s vision, writing about and eventually publishing ideas for the first algorithms intended to be executed by such a machine."
P4: "As wars came to a close, some found the vision of computers as business and war machines as (delete 'as' here) too limiting.
P4: "He wrote a 1945 article in The Atlantic Monthly, (italicize publication title) called “As We May Think.”
P4: "In it, he envisioned a device called the “Memex,” (delete comma) in which people could store..."
P8: (starting with "He then talked") "In his role in the United States Department of Defense Advanced Research Projects Agency, (delete comma) and as a professor at MIT, Licklider funded or (should this be "and"?) facilitated the research that eventually led to..."
P9: "Sketchpad, seen in the video above, (the video is below) allowed drawing ..."
one more example of this in this paragraph and in the following video
P12: "Many were truly inspired by the demo, (delete comma) and wanted to use the freedom Xerox had given them..."
Many examples of unnecessary commas used with "and" to separate two dependent clauses. They should only be used this way to separate independent clauses.
2nd to last P: "Around the same time as the release of the Macintosh, many computer scientists who had worked in computer graphics (a field started by Sutherland), (delete comma) spun off a new conference..."
2nd to last P: "This community brought together researchers interested in not only the useful output that computers could produce, but also the novel forms of input , (extra space before comma... but also delete the comma) and the interaction paradigms..."
