If it’s not, maybe you can tell me what a podcast is, and how it’s different from a YouTube video?

If I can listen to the YouTube video without needing it for visual aid… that’s just it: they’re the same thing. This wraps nicely into the video podcast thing you were whinging about earlier.

…why would I do that?

Considering your stance on this topic… why wouldn’t you? It’d be on brand.

This is not “language adaptation”, this is a complete erosion of the meaning of the word.

I really was hoping you’d say this. Semantics. Again. Language isn’t some dead unchanging thing. It morphs and adjusts with culture and technological changes.

By your logic you must surely lament the death of ancient ‘proper’ English circa 5th century before all those awful changes came about.

We have words for videos, they’re called “videos”, which are fundamentally different from a “podcast”.

Synonyms exist. Whether or not you choose to acknowledge them might be your business… however the fact you understood the medium being spoken about suggests quite plainly that language has succeeded here.

Podcast are not necessarily offline. You can stream them.

Ah, but initially - one name was for a live stream and the other for a recording. Streaming is ambiguous: are you streaming live or a recording? Thankfully: we do not make such a differentiation any more. I find it somewhat interesting your stance allows for such a difference to be ignored, though. Perhaps, given time, you will moderate on the remainder of this terminology. After all it’s a rather silly hill to die upon.
