It depends on the risk involved. The US stock market has returned around 7% annually averaged over a very long period of time. That’s considered the benchmark for investments with significant risk.
Credit scores didn’t exist but credit bureaus date back to the mid 1800s in the USA. Also, as others have mentioned creditors would do their due diligence and try to assert that you would be able to pay back your loans by doing many of the same things they do now.
This really isn’t some new, crazy concept like you’re making it out to be. The score has only simplified the process.
I remember talking to an older fella about his experience becoming a programmer back in the 60s (I think). He told me that he decided it was time to start a career so he went to a nearby IBM office and asked for a job. They gave him an aptitude test and then hired him the same day. He wrote code for their mainframes until he retired.
There’s no reason that a monolith can’t scale. In fact you scale a monolith the same way you scale micro services.
The real reason to use micro services is because you can have individual teams own a small set of services. Lemmy isn’t built by a huge corporation though so that doesn’t really make sense.
Somebody actually did make this as a joke years ago haha https://github.com/yarrick/pingfs
