for me the arguments would be mostly negative because:
- using it does not train your research skills
- using it does not train your creative and academic writing skills
- it is often just wrong when synthesizing text
so to me those are major cons in an educational context some positives would perhaps be:
- it is useful as a phrase bank, as it can quickly give ideas on how to put words together.
- it is alright at giving direction when starting research, sort of like wikipedia
thats all i can think of so far
