With the rise of AI, you could make an AI system read a million whitepapers if you want, or whatever amount you can feed it, and give it specific features and even ask it some innovative ways your project could improve on what exists, so that you could write a whitepaper that looks legit and great, because AI could help you write it, it will write you the best whitepaper you can think of. This means, there is really nothing important about whitepapers, there never was, because a shady person can write a good whitepaper too, there is nothing stopping them from stelaing your money after writing a good whitepaper.
I think the line "There never was" is not right to say because I have read dozens of whitepapers and am still reading many, even if most of them might be written by AI Still, reading about the project is necessary, and we can only know more and more about the project by reading its WP.
I am using AI too, like we have to download the PDF and give it to the AI, and it will read it and can give us summary and pin points, but most of the time they ignore some important information that we have to check manually, like the roadmap, team, and other similar information. I mostly look on WT.
The whitepaper of a crypto project is a primary source of information about fine aspects of the given project plan, technology, timeline, and people. Whitepaper is probably the most crucial document that describes the technical and the strategic background of a project, and even though today many of those whitepapers can be created with AI or with the help of an automation, it is still a highly valuable resource for an investor or a crypto enthusiast who wants to gain more insight into the project.
Thus, using AI in order to summarize information is indeed convenient, though it becomes helpful when it comes to using it in cases with long whitepapers. But as you pointed out the problem are that AI overlooks sections such as the roadmap, team information, or other sections that might influence an investors decision. It is still mandatory to go through these critical sections in order to get better understanding of a project under analysis.
