To count as part of this wave of "compute-intensive offerings", I will wait until the next obviously-power-hungry service comes out, and then start a metaphorical timer for about a month, which resets whenever a new obviously-power-hungry service comes out. When the timer hits 0, I will close the market. I won't be following this timer strictly, I will be resolving subjectively. So small delays would not make this market close, but large delays could.

I will use my best judgment here, but I want to do this subjectively.
