I think that after we are well beyond self-sustaining and a buyback has already occurred to raise the share price >$5 to allow institutional buying to come in, extra cash will be mainly used for growth, then once a very large growth has occurred and things are world-wide and stable, that cash that was being used for growth will then be able to slowly (over many years) be shifted into a divided as growth starts to max out and slow. It will probably be very small for the first several years to allow for maximum funds for growth but if you have a substantial amount of shares then that little bit will end up being significant and will keep the share price stable as many large holders will not want to sell due to the dividend.
