<p>This is really cool! Go is so dead simple to learn but it just lacks a few features. I feel this really fills that specific gap.<p>Go with more expressive types and a bit stricter compiler to prevent footguns would be a killer backend language. Similar to what TypeScript was to JavaScript.<p>My 2 cents would be to make it work well with TypeScript frontends. I think TypeScript is so popular in backends because 1. you can share types between frontend code and backend code and 2. it's easy for frontend devs to make changes to backend code.</p>

<p>Good article! Small suggestions:<p>1. It would be nice to define terms like RSI or at least link to a definition.<p>2. I found the graph difficult to read. It's a computer font that is made to look hand-drawn and it's a bit low resolution. With some googling I'm guessing the words in parentheses are the clouds the model is running on.

<p>One big difference is that with unwrap in Rust, if there is an error, your program will panic. Whereas in Go if you use the data without checking the err, your program will miss the error and will use garbage data. Fail fast vs fail silently.<p>But I'm just explaining the argument as I understand it to the commenter who asked. I'm not saying it is right. They have tradeoffs and perhaps you prefer Go's tradeoffs.</p>

<p>I think the argument is that the compiler does not enforce that the error must be checked. It's just a convention. Because you know Go, you know it's convention for the second return value to be an error. But if you don't know Go, it's just an underscore.<p>In a language like Rust, if the return type is `Result<MyDataType, MyErrorType>`, the caller cannot access the `MyDataType` without using some code that acknowledges there might be an error (match, if let, unwrap etc.). It literally won't compile.</p>

<p>Yeah it seems there's a bit of asymmetry between a normal lender and the federal government here where as a normal lender you might not be able to lend enough to guarantee the debtor survives. Also what the gov decides to do may significantly influence the lender's behavior. If the lender thinks there's a chance the gov will bail them out, they would probably prefer that and not give a loan.<p>Whereas the federal government can write a check for $633.6 billion and be much more certain the debtors will survive and pay it back.</p>

<p>> It cost the taxpayers nothing (in fact it made us money)<p>I was surprised to learn that the "bailout" was in fact a loan that was repaid with interest for a "net profit of $121 billion" [1] rather than just giving the banks money. After learning this, I polled many people around me and few had understood the terms of the transaction. So I think there may be significant public misunderstanding there.<p>Even if people do understand it was a loan, there's an argument to be made that the money could have been spent in better ways (e.g. early education improvement, preventative healthcare etc. that also give long term returns in preventing crime and reducing healthcare costs). If you believe not giving the loans would have caused the total collapse of the economy and worsened of all of those things (crime, healthcare, education etc.), then it seems a worthwhile investment. But not everyone may share that perspective.<p>> What part of that are people mad about, and why?<p>Another element of the controversy was the payment of $218 million of bonuses to the executives of AIG which was being bailed out and effectively run by the federal government [2]. Apparently the government allowed the bonuses because Geithner said there was no legal basis for voiding the bonus contracts.[3]<p>Some people think controversy over government mortgage relief spawned the Tea Party movement based on this speech by Rick Santelli [4] about his dissatisfaction with the government's bailing out the "losers" who couldn't afford their mortgages.<p>Some people also feel there could have been more regulation of the financial sector or breakup of big banks [5] or more stipulations attached to the loans.<p>Just some suggestions based on my understanding of the history.<p>[1] <a href="https://en.wikipedia.org/wiki/Troubled_Asset_Relief_Program#Impact" rel="nofollow">https://en.wikipedia.org/wiki/Troubled_Asset_Relief_Program#...</a><p>[2] <a href="https://en.wikipedia.org/wiki/AIG_bonus_payments_controversy" rel="nofollow">https://en.wikipedia.org/wiki/AIG_bonus_payments_controversy</a><p>[3] <a href="https://youtu.be/uYJLyGoWbzY?si=geM87strQlH7EURN&t=1079" rel="nofollow">https://youtu.be/uYJLyGoWbzY?si=geM87strQlH7EURN&t=1079</a><p>[4] <a href="https://youtu.be/5v1EtiEuSEY?si=055bAuiZiIq-YHXy&t=3023" rel="nofollow">https://youtu.be/5v1EtiEuSEY?si=055bAuiZiIq-YHXy&t=3023</a><p>[5] <a href="https://en.wikipedia.org/wiki/Brown%E2%80%93Kaufman_amendment" rel="nofollow">https://en.wikipedia.org/wiki/Brown%E2%80%93Kaufman_amendmen...</a></p>

<p>This is my second attempt learning Rust and I have found that LLMs are a game-changer. They are really good at proposing ways to deal with borrow-checker problems that are very difficult to diagnose as a Rust beginner.<p>In particular, an error on one line may force you to change a large part of your code. As a beginner this can be intimidating ("do I really need to change everything that uses this struct to use a borrow instead of ownership? will that cause errors elsewhere?") and I found that induced analysis paralysis in me. Talking to an LLM about my options gave me the confidence to do a big change.</p>
