It's a truism and as such it doesn't really say anything meaningful. The limiting factor is "sufficient compute resources". Assuming that a general artificial intelligence is possible and can be coded as a program, then whatever that program is could be created by something as dumb as a random number generator.

Of course, given that it seems obvious that any program which encodes a general artificial intelligence will be complex, I expect it would take longer than the expected life of the universe to generate it with a random number generator using all of the compute resources available on the planet. So it's theoretically possible but practically impossible, which makes the OP's statement essentially pedantic.
