>the whole PC gaming market will evaporate.
I'm not happy about the current GPU situation, but there's no way this is true. Will PC be impacted? I'm sure. Honestly, it might be for the better. My Steam Deck uses 15W, and the graphics it can put out are good enough for me. Improvement over time is nice, it doesn't have to be so fast. Gaming won't lose anything by slowing down its graphics cycles.
