I do not miss dealing with csv files in the slightest.
You get this backwards. Tabular structured data to store are ubiquitous. Text as a file format is also ubiquitous because it is accessible. The only actual decisions are about whether to encode your variables as rows or columns, what is the delimiter, and other rules such as escaping etc. Vars as columns makes sense because it makes appending easier. There is a bunch of stuff that can be used for delimeters, commas being the most common, none is perfect. But from this point onwards, decisions do not really matter, and "CSV" basically covers everything from now on. "CSV" is basically what comes naturally when you have tabular datasets and want to store them in text. CSV tooling is developed because there is a need for this way of formatting data. Whether CSV is "good" or "ugly" or whatever is irrelevant, handling data is complicated as much as the world itself is. The alternatives are either not structuring/storing the data in a tabular manner, or non-text (eg binary) formats. These alternative exist and are useful in their own right, but don't solve the same problems.
There are at least 3 knobs to turn every time you want to parse a CSV file. There’s reasonably good tooling around this (for example, Python’s CSV module has 8 parser parameters that let you select stuff), but the fact that you have to worry about these details is itself a problem.
You said “handling data is complicated as much as the world itself is”, and I 100% agree. But the really hard part is understanding what the data means, what it describes. Every second spent on figuring out which CSV parsing option I have to change could be better spent actually thinking about the data.
Apple macOS has had to invest enormous amounts...
Pick your distro of Linux has had to invest enormous amounts...
None of them a perfect and any number of valid complaints can be said about any of them. None of the complaints make any of the things useless. Everyone has workarounds.
Hell, JSON has had to invest enormous amounts of effort...
Want to do the same with csv? Good luck. Delimiter? Configurable. Encoding? Configurable. Misplaced comma? No parse in JSON, in csv: might still parse, but is now semantically incorrect and you possibly won’t know until it’s too late, depending on your parser. The list goes on.
