Technologically speaking, heres what I hope for.

First and foremost will come asteroid mining. The increase in global emissions and the need for exotic resources in developing countries will drive for an opening to fund mining asteroids, along with something else, a dream of a lottery. Were already talking about asteroids with enough gold to buy the entire planet. So if more companies drive for space like space-x, blue origin, and Virgin we could see the launch of drone ships to send asteroids into our local orbit for more streamlined mining, the launch of the asteroid redirection test is also proof of this.

I see asteroid mining becoming mainstream by 2075.

Nearly simultaneously is the continued development of 3D printing technology, specifically it reaching near star trek levels of complexity. Perhaps not genuine molecular reconstruction like in actual replicators, but very definitely the next best thing. With an influx of raw materials becoming available from asteroid mining, supplying a type of industrial 3D printer could become a lucrative business opportunity. Offering a service to literally “print” goods like cars, computers, designer art and clothing. The option to further personalize everything you own would be very profitable. This of course will continue until the technology gets refined enough where people could own a personalized version in their home. They could take an ild cell phone put it in one of these devices and it would recycle the raw materials then print the new version. So instead of purchasing items from companies, you could own the raw materials then just download the template to make the product, or of course make your own.

I see highly proficient 3D printers becoming commonplace by 2100, with its precursor industrial design releasing in the mid 2050’s.

Come the turn of the 22nd century, genetics will become the next big thing. I know not what geo-political ideals will govern people at the time, but I do know that for few, the benefits will be far too tempting. Gene exiting to create designer babies with specified muscular structures and unique intelligence, a baby created by brain surgeons to be the perfect brain surgeon. Splicing genes to remove genetic defects and improve immune response, no more dementia or cancer. Creating the ideal humans to colonize the now partially populated worlds of the solar system, the birth of the first true Martian.

Gene editing’s damage will have been done by 2150.

Not really the development of new tech, but of a new structure. A Dyson swarm to harvest the photo-electrical energy from the sun providing power to all humans on all worlds in the entire solar system. If done properly, this project would have actually stared back in 2050. It would just take that long to build. It should be done exponentially, the resources are gathered to design 1 solar panel, that solar panel is sent to the sun and starts collecting power, the power from that 1 panel allows for the creation of 2 more. 2 becomes 4, 4 to 8, 8 to 16. So on and so on most likely for a lot longer than just 150 years, but by then for the growing humans it will have reached an equilibrium where it is now generating enough power to take over for all other forms of power generation.

A Dyson swarm will be able to provide power for all of humanity by 2200.

The kindles have been ignited, at this point humanity now has access to for their use, a near limitless supply of resources, power, and the technology to turn those resources and power into whatever they imagine. This last century wont even take place on earth, it will be humanities first steps into the greater universe. I foresee the creation of a interstellar class starship. What drives this starship, my 3 main guesses would be advanced ion propulsion for a sleeper ship (long lasting fuel large payload for a long slow voyage) gravitational wave propultion (massively powerful but also heavy engines, fast travel time ‘relatively’ but a smaller payload) or automated. Humanity may reach a point in only those 200 hears in our solar system where diversity looses all meaning. Humans could send out seeds on self replicating spacecraft sent across the entire galaxy giving rise to entirely new genetically isolated forms of humanity.

I see humanities first steps into our galaxy taking place by the beginning of 2300 and the end of my designated time to guess what humanity will do.
