I feel like the bigger problem isn't whether these deep research products work, but rather the raw material, so to speak, that they're working with. For example, a lot of the "sources" cited in Google's AI Overview (notably not a deep research product) are not official, just sites that probably rank high in SEO. I want the original source, or a reliable source, not joeswebsite dot com (no offense to this website if it indeed exists).
