For dipping your toes into a new topic I think it’s perfectly fine. It helps to provide useful pointers for further “research” (in a sense that would meet your requirement) and also manages to provide mostly accurate overviews. But sure, to really dive into this, LLMs like ChatGPT and co. are just some low-level assistants at best and one should go through the material themselves.

Perplexity does a good job as LLM-search-engine-combo.
