Person made a claim about intelligence becoming a product (arguably it has been on the market for a long time; see knowledge workers) "that you can [now] quantify and buy with electricity". That points to the rhetoric often pushed that humans are [objectively] special, because intelligence. Or at least were. And it's the reality wakeup call that's driving that feeling of awfulness/despair/outrage/whatever else, as has been posted about here and elsewhere multiple times.
This is a problem of wealth distribution and it's fair to feel in a such way if your edge as an employee is being taken away. Being or feeling special is irrelevant.
You're shifting. Nothing was said here about job security. As stated, this is someone who feels awful because intelligence is now a thing that's available to machines. A similar - albeit lighter - tone to this[0], where in the article the author describes being in some "spiritual crisis", and that "The creation (or even the pursuit) of novel mathematics is one way that humans have historically accessed the ineffable and encountered the divine and mystical". Have a look at some of the comments, if you never saw it before.
