One question: is a new scientific discovery / invention really a world progress?
We've seen this countless times: a new revolutionary invention comes out, someone writes about it, and then 3 months later nobody is using the new invention and nothing has changed, was it really progress?
I think it is more interesting to post the adoptions / results of new laws and scientific inventions rather than something that still has a long way to go before really making a progress in the world.
