It is interesting to read some of the scripts and see things which did not make it into the final aired versions, but in some cases might have been an improvement. In "The Offspring" Admiral Haftel uses the term "effective isolation" to explain why Data's development of Lal shouldn't take place solely on the Enterprise, but this term is given a broader definition in the script. When Haftel and Picard argue over the circumstances, the admiral points out that the M-5 debacle was in no small part caused by Daystrom's penchant for working in isolation and that it contributed to his breakdown in "The Ultimate Computer," as well as to the instability he unwittingly transferred into the M-5 unit. This, to me, gives some of Haftel's arguments a more clear weight than what is seen in the aired dialogue; his goal is to ultimately prevent such a circumstance from creating a new potential M-5 down the road.
