My likely totally wrong predictions.
Medicine
-Cybernetics will become commonplace. Go blind, here's a bionic eye. Lose an arm, here's a new one.
-Replacement organs will be grown in labs, eliminating the need for organ donation.
-Nano-medicine will continue to improve to the point where cutting someone open to perform surgery seems barbaric.
Transportation
-The hydrogen economy will replace petroleum. Fuel cells will replace engines as they have all the benefits of electric without the range and refueling drawbacks.
-Cars will become self-driving in order to reduce increased traffic congestion as urban environments grow.
-Space flight will become commercialized and become cheaper. LEO space craft will replace air travel for long haul flights, greatly reducing transport times.
-Toronto will finally build a fourth subway line. (Very optimistic)
Electronics
-Quantum computing will replace binary computing
-By this time, the internet will have long replaced other telecommunication methods. Everything will be cloud based. Desktops, game consoles and laptops will cease to exist. They will all be replaced by some form of tablet or smart phone-like device, which act as online portals.
-Retina displays will become common should monitor panels continue to exist. Holographics will become commonplace.
Agriculture
-Genetically modified foods will become accepted, greatly reducing hunger.
Urban planning
-Cities will continue to grow upwards, eventually replacing suburbs with towers. These buildings will be semi-self sustainable. Buildings will generate some of their own electricity through photovoltaic glass. They will feature shops and office space. A greater emphasis on living and working in the same area, or the same building.
-Roads will be able to communicate with cars to tackle with the increased congestion
