What happened was that a lot of Lisp/AI companies had to let people go. Amongst them from the Lisp Machine companies: LMI, Symbolics, TI, Xerox, ... but also Lucid and a few Expert System vendors. Some of these people were very experienced developers. There were only a few Lisp/Lisp-like companies/projects to go: Apple/Dylan, Harlequin, Franz, Clozure, ITA, ... They also worked on Java and .net infrastructure and languages.

Dan Weinreb wrote an object-oriented database at Symbolics -> Objectstore was founded by former Symbolics people. Their C++ database was said to be influenced by Symbolics Statice.

Patrick Dussud from TI went to Microsoft. Dave Moon went to Apple. Gary Palter worked for Clozure. Steele worked for SUN on language design (Java, Fortress, ...). Weinreb later went to ITA -> worked on the flight search engine written in Lisp. There are a bunch of other examples.

A bunch of language infrastructure or even language designs was influenced.
