> The business owners I know who have been successful historically are seeing a 2x improvement and are completely unsatisfied. It's shattered their perspective on what is possible, and they're rebuilding their understanding of business from first principles with the new information.

Why are they not satisfied with the 2x improvement? Could you give an example of the "rebuilding" that you mean?

No, not at all actually. But I had a lot of applications where at somepoint we needed to add storage of currency in the database. It became relevant for billing or other features. This without the app itself being financial in nature.

Personally the lack of a decimal type make SQLite a no-go for me. Its too much of a hassle to do financial operations completely on the application side.

Why is EF regarded as such a good ORM? I've encountered countless bugs in different repos related to its stateful nature after many years in .NET. Personally I found it completely illogical for my ORM to maintain state. I just want it to hold my schema and build queries.

Yes, european roads are not as wide, since they make place for proper sidewalks and bike lanes. Another advantage is that narrower roads make drivers drive more carefully and slowly, reducing accidents even further.
