Not saying csv doesn’t have its issues, but I don’t think the author made a convincing argument.
A lot of the issues the author brought up didn’t sound that bad and/or it sounds like he never looked at the source data first.
If you’re doing work with large datasets, I think it’s a good practice to at least go and look at the source data briefly to see what to expect.
This will give you a good idea of the format it outputs, data types, some domain context, etc. or some combination thereof and I don’t think it even takes that long.
Also, it reminds me of the arguments against excel in a way. Most people know what a csv is, more or less how to open it, and don’t need too much context when discussing the file. Someone will quickly understand if you tell them the file isn’t delimited properly right away. These are pros that shouldn’t be taken for granted.
Again, I’m not saying csv doesnt have issues or that there aren’t better alternatives, simply that I didn’t find this particular argument convincing.
