Ed Zitron doesn't say that AI doesn't work, that its impact on the world will not increase. He's basically saying that (1) the current data center investments are based on unrealistic revenue projections and (2) hyperscalers are using accounting tricks to move around "money" in a circular way to make it look like more money is already flowing to AI.
You can believe all of that and still believe that AI (as in "LLM based services") work, are useful and will probably see their usefulness grow even more. Just not in the magnitude necessary to make the current investments make sense.
