This question already has an answer here:
I got the storyline of this book series (I believe it was a series) told to me by a colleague at a former workplace but I can't remember the name of the author or of any of the books in the series.
The first book is about a couple of college students who find a way to relatively easily open portals to pretty much wherever they want to go.
One day, NASA (?) finally succeeds in sending astronauts to Mars (?). When they have just left the spaceship, one of them suddenly gets a tap on the shoulder, and when he/she turns around, these college students stand there in their homemade space suits, chuckling.
I believe these students later also start a company that helps other organizations establish themselves on other planets, or perhaps even "conquers" and sells planets to other organizations.
A later book in the series also describes a system that lets people upload their minds to the cloud. Some people choose to live solely in the cloud as virtual creatures, only deciding to "descend" into a "flesh" body when they need to perform some task that requires them to be in physical form.
Some people also choose to live in physical form but as several entities, or clones, and sync their mind between the clones through this system, basically allowing them to, for example, run a one-man company with several "instances" of the same human who all share their knowledge and all know exactly what all other clones know in the same moment, effectively creating a super-efficient team of workers.
Anyone knows what book series (or is it only one book?) I might be talking about?
