Some tools are fads, some make you less of a thinking person.
When I faced a second wave of IDEs I figured that any IDE is a fad - there will be better IDE in near future and your boss will require you to use it.
The use of IDE can make you know less about project at hand, because you always can investigate, as opposed to internalize/remember. The difference? If you know internal relations, you can judge changes easier. You are better programmer that way and I would say a better person.
The same goes to LMs - they help you not to know/remember and/or create thoughtfully. LMs constrain you to not know fully.
