The Tomorrow Man: In conversation with futurist speaker Thomas FreyJan 18(AZINS) By 2050, the world's most populated countries will be India, followed by China, Nigeria and the US. Without people, there's no economy. So India has the potential to be the biggest economy," says futurist speaker Thomas Frey.

He believes that there's a lot going for India—highly-educated intelligent individuals, more socially connected people and ability to work together in ways you'll never see elsewhere.

"I was at a Bollywood set, after the first shoot, a new set was put up in no time with new paint work, lighting, furniture; the space was completely transformed. In most other countries, it would take much longer." But what should India to leap frog other countries? Frey points us to some futuristic technology solutions:

Single Wi Fi hub for the whole country: It will be more efficient and being constantly connected may reap benefits we can't necessarily think of right now.

Driver-less technology: It is the future. Tesla and Ford are working on it, they are in the testing stage. Cars symbolise freedom. Everyone wants one and companies sell them till cities become dysfunctional. So you're stuck in traffic most of the time and the whole purpose of cars is lost. That's because cities aren't equipped to handle the infrastructure requirements. Driver-less technology will make movement far more fluid and current highways are designed for human drivers, so these cars may require different ones—you may need fewer street lights, automated repair work, etc. Elon Musk says you'll be able to summon driver-less cars even from 1000 miles away. As cars will fetch you whenever you want, you may not require garages and parking places that currently occupy so much space.

Contour crafting: Based on 3D printing technology, contour crafting will soon not only be able to print external structures, but also wires, kitchen sinks, roofs...in less than a day. China's Windsor Technology, used it first and the country is leading the way. Architects will love it as they'll be able to create free-form structures that aren't possible today. India should take what's available and improve it; all countries have different requirements. It can offer a lot of creative solutions such as making buildings for a very odd-shaped space, easier.

Sensors: They are tiny, easy to produce and inexpensive. More and more sensors are being added to cell phones. By 2022-32, there will be about a trillion sensors that will give you information about moisture, light, chemical composition, the works... from all surfaces. All this information will open the door for data analytics, so the one with the most data will win.
