Because when you have decent savings. It's easy to never pay a credit card late fee in your life.

When you are living paycheck to paycheck, it's a lot harder to avoid going over. Then, even a small amount over can incur late fees, and if you can't pay it off for even a month, it results in a decent amount of interest.


I don't think that is getting at the main confusion. It is pretty clear how, if someone can't pay their debt back, they're worse off. The confusion is that a credit card is a short-term smoothing tool. The point is to let merchants assume customers are good for it instead of going through the whole process of checking with a specific bank or expecting people to carry physical proof that they have the money. Using a card can't get someone ahead, the bank is expecting to charge the customers more than they give them.

So why is it necessary for these people to be using a credit card if they can't pay it back? Especially if they have an average income that is sufficient to cover their lifestyle. If they're going to be strictly worse off after engaging with a system, why are they engaging with it?

I lost you there a bit. Why can't debit card serve the same purpose?


It can and does in my experience. I suppose my question is me basically asking for a reminder of why rational poor people are using credit cards. I've always assumed they were a tax on people with no impulse control and/or poor mathematical understanding.

It is easy to see how someone with no money would take out a loan via a credit card and be unable to pay it back at all. But if they can pay it back, then outside of very rare instances why can't they arrange their affairs so they have the equivalent amount of savings up front? Their income is at least equal to their expenses on average in the short term, they can't be using credits cards to cover long-term imbalances because the interest is too punishing. If their expenses are experiencing variances then there must be opportunities to put aside an emergency fund.

I don't see how the math checks out that they need and can afford a credit card if they can afford to pay some sort of "poor tax". If you can afford the extra cost of credit card interest, you can afford not to have one. Otherwise where are the bank's profits going to come from?


Gpt-4o, in my unprofessional opinion, is miles worse than the old gpt-4. I believe it has higher scores on benchmarks, but only because it spits out paragraphs and paragraphs of useless information.


I've done the same, and it's decent, but in ML having the minor bugs that chatGPT introduces was awful for me to debug. Like, it doesn't fail catastrophically, but it just gave me really bad models. I basically got poor performance at the end for all of my models and didn't learn enough from it to debug the issues. At the end of the day, pytorch was way simpler to just learn. Have you gotten good results in some models using chat gpt with pytorch?


I get the idea, and I've considered using AI similarly, but one thing I realized: Being stuck is often the time where you learn the most. (And when you find out how to un-stick yourself is part of the most enjoyable parts of engineering).

Having the immediate aid of an LLM in a lot of ways also does hurt your reasoning capabilities in my experience. I'm curious how you would address this.


I believe this was in a pre-AI world. With AI you don't expect developers to dig through thousands of websites to find out why something isn't working. I will just ask ChatGPT because it saves me time. In the context of learning, students usually look at answers directly because they don't have a lot of other options currently. with Edmigo, we're trying to give them hints instead of telling them the answer directly so they can learn to solve on their own.


Curious where you found the 1/17 statistic?


It is an internal metric from a College that offers kids GED/remedial-high-school-level math prep classes for remote students. There are various reasons a student may be unable to physically attend classes, and remote 1-on-1 instruction is not in the budgets. The rate for curriculum completion is a very low 1:17 for self-directed study.

The learning outcomes for students are often terrible for this path, but perhaps good if you charge for the tutorial service I guess. Attrition rates are not something institutions proudly promote in public.

YC seems to down-vote anything that deals with a data-driven reality. lol =3

Interesting points. but not very student can afford or has access to group studies or human tutors right?


In my country it is the law, that the state must educate you to at least high-school level free of charge. Regardless of the challenges one may face along the way (protects those who are autistic, blind, deaf, poor, paralyzed, or incarcerated etc.)

In introductory and undergraduate academics, the departments will usually offer unstructured TA lab hours for those who seek additional help understanding material. However, the reality is "A" level students do not require good teachers, as their grades are usually not correlated with instructor proficiency (often due to a 3 year head start from out-of-band after-school tutoring services prior to the conclusion of grade school.)

The danger from LLM contaminating long-term memory recall from an erroneous primacy effect is a concern.

Have a nice day, =3


LLMs kind of are, but imo it never meets up for a


Not easily for these large scale models, but theoretically maybe


From what I can tell, the engine he plays, Rybka, is an alpha beta search engine that is rated around 3000 elo? I'm not sure how to compare it with Hikaru being ~2900, but it seems like a fairly "even" match-up without a crucial exploit being the reason for it losing.


Still a Linux noob, but I'm recently learning that you can do simple things like this in bash and the fact that it just... works is incredible. Thanks for the suggestion, I think I'll try this one


You can use a multidimensional Kalman filter to do many things


But that does not really come close to answering the question.
