World powers change and shift with changes of technology, climate and needs for resources. Countries rise to power because they are in the right place at the right time, even if monarchs and nationalists will always attribute it to God preference or other self-serving reason.

> The first century of Portuguese discoveries saw a successive stripping away of layers of medieval mythology about the world and the received wisdom of ancient authority – the tales of dog-headed men and birds that could swallow elephants – by the empirical observation of geography, climate, natural history and cultures that ushered in the early modern age.

Technology brings societal change. The world has been becoming smaller with help of each new technological step. Societies can fight it, but it is unavoidable. So, I hope that we focus more on building a good world for us all using technology to improve all our lives.

It would be interesting to imagine a uchronic world where Portuguese has become the lingua franca of the world.

As a Brazilian, the whole improbable (and beautiful) history of Portugal raised by the "Navegações" and how badly they bottled the whole imperium (especially after the Brazilian independence, but one can argue that João VI opened the ports) and the sheer amount of lack of vision in not investing in production is something that will always amaze me.

One can say that it was one of the longest imperiums in history (ending in 1999 with Macau???), but every time that I spend some time in Portuguese cities, I feel just bad. The good thing is that Brazil will carry its tradition for posterity nevertheless.
