How will our earth look in 2050? What are the major changes that will occur by year 2050 related to technology and its components?

One can only hypothesize how our Earth will look, especially in terms of technology, in the year 2050. We can use our progress over the last 50 to 100 years to make some educated guesses. 

A few of the areas where we have made tremendous progress include transportation and communication. More novel and environmentally-friendly transportation means are to be expected by 2050. We are already moving in the direction of electric cars and hydrogen fuel...

One can only hypothesize how our Earth will look, especially in terms of technology, in the year 2050. We can use our progress over the last 50 to 100 years to make some educated guesses. 

A few of the areas where we have made tremendous progress include transportation and communication. More novel and environmentally-friendly transportation means are to be expected by 2050. We are already moving in the direction of electric cars and hydrogen fuel cell based automobiles. We can possibly expect all of our transport means to be based on fuel cells by 2050. Self-driven vehicles are likely to be the norm. 

Similar progress has been achieved in communication in the last 50 years. We can expect extremely high-speed data transfer directly to headsets or glasses for day to day operations such as calling, internet surfing, online transactions, navigation, etc. One can expect laptops and cellphones to be obsolete by then. 

Given the global warming fears, we can expect that people would have moved to 100% renewable energy generation by the year 2050 and fossil fuels may already have been mostly exhausted. We can expect to see more sky-scrapers and high-yielding agriculture practices. Better healthcare and more advances in medicine are also to be expected.

Hope this helps.
