well, I can't say for sure if the world will be a better or worse place in 25 yrs from now, but this is how I see it happening yeh, I think on the one hand the world will change for the better, while another part will be worse.
for example In the technology, everything will be different and much better.
Many new machines will be invented, which in turn will make humans goe xtinct in their own thurst for power.
