This is a strawman that keeps being brought up.

There's no tool out there that generates log files it cant itself read. So there's not going to be any "oh gee I have these files being generated and nothing can read them" situation.

However, there is just about near-zero system out there that generates text logs that it can itself read. Text logs are write-only for most logging systems, while all binary logs I know of are read+write.

Stepping back though this entire argument is absurd. Thinking about "whatever will those people do 40 years from now with the tools of today" is fairly braindead once you understand that the quality of the tools will affect their longevity. So if the logging system becomes an actual, factual problem over time, the tools will die off by naturally-artificial selection.

I have already worked on very basic embedded system where you only way of getting logs is connecting to the device using a serial line, and after fiddling a bit with the baud rate, you can get some readable output.

In this case, you can't really do anything from the device itself.

Arguably, this is not the use case for binary logger but I was originally addressing the "40 years old logs" argument, that do exist in the real world.

There are plenty of tools that don't read their logs - more precisely, computer units where you don't log in, units that you don't operate on console. Embedded devices that perform some function and also keep some log, but which cannot be used for reading that log. You will need to read that log using something else. Plain text (ASCII, and now ISO Latin and UTF-8) is a fairly stable format for everything, and will be for the next 50 years.

People usually read log files because something went wrong, like a system crash, why do you assume the OS that generated the log file will be readily available?

It isn't a strawman at all. It's a real problem that exists today for folks who need to access old documents from the 80s, for example.

If only. I've used two such systems myself.

When the tool for your binary data file says "data corrupt" when you try to open it, what do you do?
