If someone cites some of your programming work 50 years after you finished working on it then you must have done something right.

From what I have heard from my father and others, editing punch cards was hell itself. The fact that TECO managed to bridge the punch card and hard disk storage eras could be viewed as some sort of miracle.

On another note, it it seems that Dan Murphy, who created TECO at DEC in 1962 - 1963, is still going strong. In 2009 The IEEE Annals of Computing History published this article authored by him (warning: pdf): http://tenex.opost.com/anhc-31-4-anec.pdf and earlier this year he updated his personal website: http://www.opost.com/dlm/
