The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race. The vices of mankind are active and able ministers of depopulation. They are the precursors in the great army of destruction, and often finish the dreadful work themselves. But should they fail in this war of extermination, sickly seasons, epidemics, pestilence, and plague advance in terrific array, and sweep off their thousands and tens of thousands. Should success be still incomplete, gigantic inevitable famine stalks in the rear, and with one mighty blow levels the population with the food of the world.
Malthus T.R. 1798. An essay on the principle of population. Chapter VII, p61

At some time in the relatively near future, we will have both the computing power and the brain knowledge to be able to create artificial realities that we will be able to plug our brains into that will give no indication that they are anything but real. We will be able to create any kind of reality, any kind of experience you can imagine.

Once a civilization is able to do that, it may very well be that they will have no other desires beyond increasing their computing power, extending their life spans, and protecting themselves from planetary disasters. This might be the key to the fact that we have not detected any advanced civilizations.

Justo Gallego Martínez (also known as Don Justo) is a former monk who has been erecting a cathedral in the town of Mejorada del Campo, Spain, since 1961.

It is being built on a plot of land he inherited.  He had to leave the monastery where he had been a Trappist monk for eight years after contracting tuberculosis.  He promised that he would build a shrine in honour of the Virgin Mary Nuestra Señora del Pilar (Our Lady of the Pillar), to whom he prayed to throughout his sickness, if he recovered.

Don Justo usually begings his workday at 6am and works for ten hours a day, except on Sundays.  He is helped sometimes by his family and local volunteers but mainly the work has been accomplished himself.  Most of the building materials are scavenged or donated by local construction teams, looking around, one can see columns made of concrete-filled plastic buckets or air ducts and stairs whose lips are formed from coils of wire, among other things.
