We live in an age where hand-held computers which are always connected to a worldwide communications network are ubiquitous. Where genetic modifications are a tool we use for medicine (insulin is grown from genetically modified bacteria which produce human insulin, for example) and food. Where self-driving cars are real. Where remotely controlled airplanes have been making a huge impact on the battlefield. Where bionic prosthetic limbs which respond to neural impulses are becoming more and more commonplace. Where cures for AIDS, deafness, blindness, cancers, and paraplegia are advancing day by day. Where anyone with a computer and the right CAD files can have items manufactured by 3D printing or CNC machining by ordering through a website. Where machines can perform near real-time speech-to-speech language translation. And where a business man talks about putting tens of thousands of colonists on Mars in his lifetime and he's taken seriously.

What will the next few decades hold? Memristor based computing. Graphene based electronics. Nano-tube based materials. Terabit/s wireless networking. Space colonization. The ability to repair or replace nearly all defective or missing body parts and organs.

And what will the next century let alone several centuries hold?
