Intelligence is about learning from few examples and generalising to novel solutions. Increasing compute so that exploring the whole problem space is possible is not intelligence. There is a reason the actual ARC-AGI price has efficiency as one of the success requirements. It is not so that the solutions scale to production and whatnot, these are toy tasks. It is to help ensure that it is actually an intelligent system solving these.

So yeah, the o3 result is impressive but if the difference between o3 and the previous state of art is more compute to do a much longer CoT/evaluation loop, I am not so impressed. Reminder that these problems are solved by humans in seconds, ARC-AGI is supposed to be easy.
