Very little concept of security, privacy and a default paradigm of "lisp assumes it owns the environment". This may no longer be true, but it's a large barrier

Very little concept of security, privacy and a default paradigm of "lisp assumes it owns the environment". This may no longer be true, but it's a large barrier against being adopted in many industries. That and it's kind of hard to do modern graphics with many implementations.... although they can do html serving pretty well. LISP environments may be the start of GUI, but that code is largely locked up, or in systems that can no longer be used (I think?) Anyway, all stuff worth putting some attention on! (note : just a lisp fan, and only an edge one, so likely no longer accurate on many points Most of the above came from reading 50s through 90s texts, and trying lisp environments at the time)
