He doesn't actually say that, the (very biased and polemical) article writer seems to have made that up. The actual quote is:

"Us self-claiming some [artificial general intelligence] milestone, that's just nonsensical benchmark hacking to me. So, the first thing that we all have to do is, when we say this is like the Industrial Revolution, let's have that Industrial Revolution type of growth. The real benchmark is: the world growing at 10 percent. Suddenly productivity goes up and the economy is growing at a faster rate. When that happens, we'll be fine as an industry."

That's a completely different statement from "AI is generating no value"!
