And since we know the resources will last for a *long* time, we can estimate that this could continue for an inconceivable span of time.</div><div><br></div><div>Great Filter arguments suggest that either the the Filter is behind or ahead of us. If one thinks it is behind us, there is no reason to think we will have a short span. If it is ahead it is reasonable to say that we may have a long span if we survives (unless the explanation if some form of iterated future filter). </div><div><br></div><br><br>Anders Sandberg, Future of Humanity Institute Philosophy Faculty of Oxford University</body></html>
