Developments of 2030's

• Personal computers will have the same processing power as human brains.

Computers less than 100 nm in size will be possible. As one of their first practical applications, nanomachines are used for medical purposes.

• Highly advanced medical nanobots will perform detailed brainscans on live patients.
• Accurate computer simulations of the entire human brain will exist due to these hyperaccurate brainscans, and the workings of the brain will be understood.
• Nanobots capable of entering the bloodstream to "feed" cells and extract waste will exist (though not necessarily be in wide use) by the end of this decade. They will make the normal mode of human food consumption obsolete.
• After the year 2030, nanotech-based manufacturing will be in widespread use, radically altering the economy as all sorts of products can suddenly be produced for a fraction of their traditional-manufacture costs. The true cost of any product is now the amount it takes to download the design schematics.
• By the later part of this decade, virtual reality will be so high-quality that it will be indistinguishable from real reality.
• The threat posed by genetically engineered pathogens permanently dissipates by the end of this decade as medical nanobots--infinitely more durable, intelligent and capable than any microorganism--become sufficiently advanced.
• A computer passes the Turing test (2030), meaning that it is a Strong AI and can think like a human (though the first A.I. is likely to be the equivalent of a very stupid human). This first A.I. is built around a computer simulation of a human brain, which was made possible by previous, nanotech-guided brainscanning.

The most likely year for the debut of advanced nanotechnology. Some military UAV's and land vehicles will be 100% computer-controlled.
