The brain does more than computers: the brain builds its internal structure all by itself. When was a computer able to evolve from a bunch of transistors laying on the table? Also, it uses very little energy and is resilient for 80-100 years, compared to the computers of today, its apples and oranges.

What if the AGI will prefer to build virtual worlds and societies of virtual agents instead of grand space domination ? Even humans prefer games to reality nowadays (or a large percentage of us do). If we're part of such a sim, then it would explain the lack of external signals from extraterrestrial aliens or AGIs.
The probability that AGI will appear and create amazing simulations is much larger than that of picking up signs of life in the vastness of space. Also, by replacing physical with sim we can do all sorts of things such as use less energy, recover from any accident, hack our own brains/minds, even immortality.
