Unless increasing costs of childrearing is its own way of creating a limit. >Still only a finite quantity of stuff in any given light cone upon which to record the state. But we're not going to reach that limit. For each increase in population*, we can increase the suspension/decrease speed and no one will even be able to notice. Growth is 'infinite' here inasmuch the growth function is monotonic - but it's asymptotic, and the total energy expenditure is always finite. Also, we're talking about such a huge timescale, one wonders what people will discover that could upend our picture of the universe. * Which again, doesn't have to happen under the definition of growth the article used.
