It points to string theory having no predictive capabilities due to multiple-universe issues, we just happened to have evolved in a universe where the (randomly selected) parameters allow for element formation and life:

Nor such attempts will be meaningful in the future. All this is an environmental coincidence. Just take it as is and live happily ever after. This is nothing else than the anthropic principle in its extreme realization, with a religious (or philosophical, if you put it milder) flavor."

So, this part of the landscape paradigm is the act of belief in today’s string theory, not supported by any evidence, and not to be supported by evidence in the future."
