Confused by article: The Earbud Tech of the Future Could Be Closer Than You Think

This is a cool article about a new technology in personal audio. However, I’m very confused by one point. The interviewee says:

"We need the hardware to improve […] in order to faithfully render the content. We’re at the same point now in audio. We’ve got hi-res wireless codecs going into these earbuds. We’re trying to make the Bluetooth connectivity more efficient, but we’re rendering that on a century-old speaker hardware that might not be able to extract all of the resolution and detail in the content.”

He’s making it sound like wireless audio (Bluetooth) is being held back by the speaker technology. But isn’t it the other way around? It’s fine that they want a new and more efficient technology for wireless audio, and it honestly looks really cool, but why misrepresent said technology (unless I’m totally off base here)?
