 Thank you for sharing that.
 The author, presumably a heavy Reddit, TikTok and Facebook user, seemed
 to have never heard about existence of computers before internet, nor
 about any computer to computer connections other than internet.  He does
 not seem to know about anything except CBBS,and that solely because it
 "resembles Facebook".
 "Early Visionary of Social Media"
 It is an adequately detailed story of his life, and mostly about CBBS
 ("a forerunner of Reddit, TikTok and Facebook")
 A dozen paragraphs about CBBS, but XMODEM barely rated a mention, and
 even there, only about its use on CBBS:
 "In 1977, he developed a protocol, called XMODEM, for sending computer
 files across phone lines; it was later used on C.B.B.S."
 . . . "For decades, his license plate read, XMODEM."
