I am perhaps glass half empty sort of person but it’s important for me how far is it to go than how far have we came. The fact is that it’s been literally 50 years since moon landing and Mars landings is still as far as it was in 90s. Cancer survival rates have improved but curing cancer is still as much as pipe dream it was in 90s. Less people are poor but eradicating poverty and providing basic education, food and health for all is still as much away as it was in 90s. I can go on but us Twitter generation take too much pride out of rather silly little things while ignoring the things that matters the most.
