except for the imaginary ones

Yeah but you don't really have to think about how it works in the background ever time you deal with that. You just know.

You learn how once and then you just remember not to do that and that's it.

And this is why f64 exists!

Please tell me you aren't using floating points with money

No. I don't have to remember that.

I just have to remember the limits and how you can break the system. You don't have to think about the representation.

So you have to remember how it's represented in the system with how the bits are used? Or you just have to remember some general rules that "if you do that, it'll fuck up."

More than a surface level understanding is not necessary. The level of detail in the meme is sufficient for 99,9% of jobs.

No, that's not all just accounting, it's pretty much everyone who isn't working on very low level libraries.

What in turn is important for all sorts of things is knowing how irrelevant most things are for most cases. Bit level is not important, if you're operating 20 layers above it, just as business logic details are not important if you're optimizing a general math library.

Since 2008.

I've worked as a build engineer, application developer, web developer, product support, DevOps, etc.

I only ever had to worry about the limits, but never how it works in the background.

The very wide majority of IT professionals don't work on emulation or even system kernels. Most of us are doing simple applications, or working on supporting these applications, or their deployment and maintenance.
