We don't know what the author had in mind, but one has to really be tone deaf to let the weirdness of the discussion go unnoticed. Take a look at the last paragraphs in the text again:
> And not very long after, 93 per cent of those horses had disappeared.
> I very much hope we'll get the two decades that horses did.
> But looking at how fast Claude is automating my job, I think we're getting a lot less.
While most of the text is written from cold economic(ish) standpoint it is really hard not to get bleak impression from it. And the last three sentences express that in vague way too. Some ambiguity is left on purpose so you can interpret the daunting impression your way.
The article presents you with crushing juxtaposition, implicates insane dangers, and leaves you with the feeling of inevitability. Then back to work, I guess.
