The problem cited by payment processor is dodged if the money is coming in as donations rather than payments, no?

It's not at all bad for an initial proof of concept.

That has always been the two big problems with AI. Biases in the training, intentional or not, will always bias the output. And AI is incapable of saying "I do not have suffient training on this subject or reliable sources for it to give you a confident answer". It will always give you its best guess, even if it is completely hallucinating much of the data. The only way to identify the hallucinations if it isn't just saying absurd stuff on the face of it, it to do independent research to verify it, at which point you may as well have just researched it yourself in the first place. AI is a tool, and it can be a very powerful tool with the right training and use cases. For example, I use it at a software engineer to help me parse error codes when googling working or to give me code examples for modules I've never used. There is no small number of times it has been completely wrong, but in my particular use case, that is pretty easy to confirm very quickly. The code either works as expected or it doesn't, and code is always tested before releasing it anyway. In research, it is great at helping you find a relevant source for your research across the internet or in a specific database. It is usually very good at summarizing a source for you to get a quick idea about it before diving into dozens of pages. It CAN be good at helping you write your own papers in a LIMITED capacity, such as cleaning up your writing in your writing to make it clearer, correctly formatting your bibliography (with actual sources you provide or at least verify), etc. But you have to remember that it doesn't "know" anything at all. It isn't sentient, intelligent, thoughtful, or any other personification placed on AI. None of the information it gives you is trustworthy without verification. It can and will fabricate entire studies that do not exist even while attributed to real researcher. It can mix in unreliable information with reliable information becuase there is no difference to it. Put simply, it is not a reliable source of information... ever. Make sure you understand that.

I blame the idea of the 00s and 10s that there should be some "Zen" in computer UIs and that "Zen" is doing things wrong with the arrogant tone of "you don't understand it". Associated with Steve Jobs, but TBH Google as well. And also another idea of "you dummy talking about ergonomics can't be smarter than this big respectable corporation popping out stylish unusable bullshit". So - pretense of wisdom and taste, under which crowd fashion is masked, almost aggressive preference for authority over people actually having maybe some wisdom and taste due to being interested in that, blind trust into whatever tech authority you chose for yourself, because, if you remember, in the 00s it was still perceived as if all people working in anything connected to computers were as cool as aerospace engineers or naval engineers, some kind of elite, including those making user applications, objective flaw (or upside) of the old normal UIs - they are boring, that's why UIs in video games and in fashionable chat applications (like ICQ and Skype), not talking about video and audio players, were non-standard like always, I think the solution would be in per-application theming, not in breaking paradigms, again, like with ICQ and old Skype and video games, I prefer it when boredom is thought with different applications having different icons and colors, but the UI paradigm remains the same, I think there was a themed IE called LOTR browser which I used (ok, not really, I used Opera) to complement ICQ, QuickTime player and BitComet, all mentioned had standard paradigm and non-standard look.

AI isn't math formulas though. AI is a complex dynamic system reacting to external input. There is no fundamental difference here to a human brain in that regard imo. It's just that the processing isn't happening in biological tissue but in silicon. Is it way less complex than a human? Sure. Is there a fundamental qualitative difference? I don't think so. What's the qualitative difference in your opinion?

Of course they don't click anything. Google search has just become a front-end for Gemini, the answer is "served" up right at the top and most people will just take that for Gospel.
