I'd have to find the youTube link to answer this one, to go into the details behind exactly why. So leave that with me for now.

I wouldn't bother. There are endless junk articles on utube and you won't find anything convincing because, really, there isn't an issue. Methinks Voodooless is just teasing you.

However, if you are going to do a conversion of Electronic-optial-Electronic the conversion will never be perfect and there will be errors introduced at each conversion. Now it is certainly possible that those errors could be small enough will not to be obviously audible but errors are still there.

Perhaps best to be less sure and not make absolute statements. Errors in that conversion are likely to be non-existent or not significant. What you do get is timing jitter in the signal (always) and that can be increased in the transmission/reception process but it is arguable whether even that is significant.

Don't we want to get from the digital data in the file to the DAC chip, to do it s work of converting this into an analogue signal, as cleanly as possible without introducing errors?

Yes but, again, you won't be introducing error in the conversion process.

I have only recently heard about i2S and not everyone is using it, so I am keen to learn and understand a bit more about it.

Unless you are a circuit designer there is nothing useful to learn and understand. I2S is a protocol designed for and good at inter-chip communication within a device. It is not a general purpose communication protocol between devices and is not robust enough for that, for talking between boxes use SPDIF or Toslink or preferably USB , or even Ethernet. All of these when sensibly implemented are good for the job and in normal use you don't have to worry about error or cables or connectors or error rates. Don't believe the FUD

In a normally operating interface, there will not be any errors in transferring the audio data. Error would be very obvious.

Oh, don't worry, basically everyone is, just inside of their DACs, where it belongs.
