If the computational requirement is within the realm of another normal day to day task, and if it cannot generally achieved with another cheaper approach, it would be contradictory to say it is staggering.

I would agree if this was an easily solvable problem with classical approaches. Clearly it is not, since even uBlock is giving up.

At any rate, "staggering" is relative. White-labeled web browsers becoming the most common GUI engine would have made an engineer's eyes water 20 years ago.
