You have probably heard of the Nanotechnology and how promising is for the future. But we actually need to think, on how many fields of humanity can actually be upgraded or take advantage of such technology in the future days to come.
So far this technology is still new for most of the people like to put on it. But some areas are already making preparations and investments in this technology since the vision for it seems pretty promising.
Keep in mind that we are talking about a technology that can affect and manipulate everything that exists and would exist.
Some of the fields and areas that want to make future use of this technology are:
Stockpiling, Production and energy conversion:
Since nanotechnology can create all kinds of stuff with precise quality, most enterprises have invested for future projects on this technology to increase the level of production and materials that can be done using it.
Defense systems and weaponry:
Well, probably not the best for humanity since atomic bombs are already a big thread. But it is almost inevitable that some armies will try to make use of such technology with purposes of defense, since nanotechnology can create advanced weapons and devices with such purpose or even make new ones that can take advantage of nanobots atomic and molecular manipulation.
This should be the number one use for this technology, since with the help of nanotechnology, most buildings can be assured and restored in ways that most people cannot do.
And even create new buildings, as long as the tools and nanobots keep progressing as expected to do the job of several men for months, in a matter of just days.
No surprise here, since most computers and those who make use of it would like to have an especial printer or device that could actually print a full 3D real object with the same exact quality as the original, and with every detail preserved (different from the so far know 3d printers from today).
This one is mostly to ensure that the containers and the quality of the food can be perfectly preserved with the help of nanotechnology creating such containers.
But also it can modify some of the food, so it can be more easily processed for the humans and keeping the flavors in ways that not all foods can today.
