"enough" hides a surprising amount of work. Mobilise the entire planet's computers for a decade, assuming a generous Moore's law increase as well, and you might count through seventeen 8-bit grayscale pixels in that decade.

Annihilate the Sun and you won't get enough energy to drive a simple counter through thirty 8-bit grayscale pixels.
