We’re talking 20 years or so here.
In 20 years we’ll be facing Big Stuff. Climate change, weather volatility, species loss, clean air, clean water, … that whole environment thing will be getting much more serious and everyone will be dealing with it in some way or another. I’m hoping it’ll make Ireland a bit more like the south of France, and it might, but whatever else, it’s going to make the simple things in life more difficult. For most of humanity that will include feeding themselves and getting clean water.
So that will make food and land more important.
In 20 years we may well have passed “The Singularity“. That’s a term coined by futurists, often with a trans-humanist bent, which denotes the inevitable point at which technology development starts happening “by itself”. This occurs as humanity’s understanding of physics and biology enable the creation of thinking machines (computers) that emulate the brain, and then androids and cyborgs begin to be used in place of people.
Certainly in 20 years technology will have changed our world even more than in the past 20. Do not imagine The Singularity to be fantasy. We are close already. The mobile phone/computer in your pocket is old technology compared with neuro-computers being tested in laboratories. Robots are already becoming remarkably similar to C-3PO in looks and mobility at least. Today the consequences are being felt in most professions as AI (artificial intelligence) takes jobs away from humans. This is what we all wanted – automatic checkout, automatic cashier, automatic accountant, automatic lawyer, automatic vehicle … The challenge now being solved is automatic creativity.
