<p>What you probably mean is puzzle solving intelligence. Humor is a form of intelligence. It's just not only about intelligence - it's also about values, and context, for instance. But all this reflects a form of intelligence. Neverthless, intelligence shouldn't be ranked, at least not in the way we are used to talk about it.</p>

<p>Yes, that sound indeed hard. Do you think it's possible by using memory usage patterns, GPU and RAM consumption levels, etc.? I didn't read this, but sounds interesting: <a href="https://arxiv.org/abs/2407.15847?utm_source=chatgpt.com" rel="nofollow">https://arxiv.org/abs/2407.15847?utm_source=chatgpt.com</a></p>

<p>I've read the paper which was referred on some news lately, and it conviced me we already passed the warning red light.<p>I've been thinking about how OSs can be improved to prevent this from happening, by establishing some shutdown machine termination, and critical memory regions which no AI software can enter, for instance, but I would love to hear other people opinions (obviously this would be just one strategy among many). Even if you don't agree we are there, how would you stop them?</p>

<p>Books are so poorly written that they are only useful because of the exercises, table of contents and as a consulting guide to see relevant equations and images. They could easily be 1/3 the size and have the same impact. 
For concepts, I only use AI.<p>And probably openstax.org is enough anyway, in terms of books. They do a better job for free that most publishers with lots of recommendations that charge hundreds. Then you have a lot of exercises provided by some american colleges that I assume will also be enough.</p>

<p>Honestly, from the stories I hear... Obviously,the money is one factor, but even if people got a little bit more money, they would still go for a PhD (at least in europe, where you don't need to go under debt so much, if you need to). The problem is that a lot of people don't even receive more money than people with Msc or even less. That's just too bad (even if in some countries this is not only illegal, but people actually follow the law - which is not something you should take for granted).<p>But even after the money consideration... you still have all the "lost credibility" in the system, because the institutions are not properly funded, and also because science is very dependent on grants,politics, and stupid criteria + nepotism and corruption inside the institutions, etc. That goes beyond PhD applications to even "who can sell the coffee in campus". On PhD apps, I will never forget when one of my housemate just said to me that he would leave the country because one teacher said to him in advance that he would not enter on PhD, because everything was bought out.<p>I think this is only the ""beginning"" of at least 10+ years of colleges having a hard time/ losing credibility year after year (sometimes because they are failing, and other times because they dare to have opinions different than people like Musk, which is not fair for academia). Either way, should I feel sorry for them? For the institutions, sure. But for the people who rule the institutions right now? My only fear is that they will be substituted by even worse individuals.</p>

<p>How do you identify bots and low quality reviews in general? 
I believe the problem exists, but I'm afraid the problem is that the platforms who perform reviews with high quality reviewers don't have enough reviewers for the reviews to appear centralized enough to be useful.</p>

<p>I don't know what tech stack you used, but very well done! :) especially considering the time I suppose you had to built such app.<p>I would make the bars that represent the months clearer by labeling the months (I just tried the demo).<p>I'm not sure what do you need in order to just ask for people its bank statements (even if it's not stored). I would check into that.  
I think people need more actionable advice (less generic, less "you need to improve on this) than just seeing the same tips over and over again, but this might be hard to implement depending on what we are talking about.<p>There are some good cheap recipes on the internet, but they might be hard to find sometimes, for instance (despite the promise of making good and affordable recipes is very easy to find, that's other thing).
In some countries, it might be hard to know who is really offering some of the cheapest services like insurance, for instance, because this is also kinda hard to simulate for some situations. 
In other situations, I also don't see how a notification that "you should spend less on parties" really goes beneath the surface of any problem whatsoever. Imagine you are dealing with an alcoholic. That not only doesn't work, but its also probably just annoying.<p>Tracking tools are cool because people need to track expenses anyway, and it's much easier to do it digitally, than to do it with a pen and paper (even if there are a ton of apps out there, with the right marketing and a little bit of luck, you can have some market share and that's great). 
AI generated advices... Each case is a case. Each person is a person. It's a ton of work, and it needs to be done carefully. If you are aware of all of this, and want to test in some situations, I will say go for it. If you want something very superficial and generic like some popular magazines and websites do nowadays, I would not invest much time on it.</p>

<p>I agree with you if you then consider the eventual need for "swarms of agents" / collaboration between different agents, so one agent can write a marketing campaign, and another one can design the billboard (everything without supervision).</p>

<p>Portugal and Spain seem to have a iberic mechanism that honestly i don't know in detail, which prevented a sharp increase (at least as significant as european counterparts) after Ukraine war.<p>My guess is that renewable adoption is necessary to decrease energy prices, but is not enough, so good policy enters the chat.</p>
