Sure there will be. Whole of Africa is suffering and calling for help. We can go there and build their society. Help them so that they can help themselves. Inside USA there are still people suffering in flood, tornado, draught, and earthquake disasters. They need help.
We cannot go to the moon. We need lot of new research effort to make that happen. New ideas and technologies will be necessary to achieve that. We will have to build the international railway system around the globe, so that we can effectively transport people.
We need a new kind of ladder to heaven, so that people can easily climb up, to find god and enrich their souls.
It is not possible to believe that people will remain idle in the world under MLE. Every day, every moment people will come up with new ideas to benefit the society, just like we are doing now.
