I don't know the exact details, but I have heard (on C++ Weekly, I believe) that it offers some advantages when linking code compiled with different compiler versions. That said, I normally avoid it and use fmtlib to avoid the extra compile time. So it isn't clear if it is a win to me. Header-only libraries are great on small projects, but on large codebases with 1000's of files, it really hits you.

My personal experience is that the increase in ads has encouraged me to subscribe to creators I like via Patreon and view content on there. If many people are doing this, I wonder if it skews the view statistics and, therefore, lowers the number of recommendations for the best channels. In turn, this makes it less likely for good channels to be discovered. The increase in YouTube ads also makes me much less interested in browsing there, and I am finding other things to do instead.

I opted for sorting by project. We live in a world where you can get most things the next day. Then, I keep a few part-sample books for common components like capacitors and resistors for modding. Even if I need a specialist component, I know what projects I have used it in before

My take is that it means founders are sharing the risk by investing in the company and by taking a smaller salary than they could otherwise. This means there is a clear motivation to get a successful exit for them as well as the VC's

It saves writing lots of boilerplate. If you implement it for a type, you automatically get: <, >, <=, >=, ==, !=
