Thanks for your input. I enjoyed the read. Let's say for the sake of discussion that everyone becomes biologically immortal. No one dies of old age anymore. (Technically nobody dies of old age at the moment, but from other factors like disease taking advantage of a weakened immune system)
Thanks for the clarification, true immortality is a greater unknown that biological immortality, since people can still die one way or the other. (Eventually everyone would die from an accident since time is infinite)
In the case of Biological immortality we may be able to develop technology similar to a nerve gear (Can't think of a reference for it directly sort of like Occultus rift meets sword art online) Where we would not need to have our phyiscal bodies do much just connect it to a system and carry on from there when you want to disconnect from reality.
Of course that's only temporary shift which might last for a long time (by mortal terms), while humanity figures out how to make Faster than light travel to colonize galaxies, immersed virtual reality would also work as a passtime instead of cryogenetics to kill some transit time, they can hang out in VR with other people in real time while heading to their new destination in the physical world.
In terms of politics assuming that we have Li-Fi (current fastest communication network) and use it to turn our technology into the Internet of things where everyone can communicate directly and jump into the network instantly, one outcome would be a decentralized governmental system, assuming we have enough automated processes going a theoreticial outcome is that due to society having a sufficient processing of resources Politics itself is not a needed instiution in its present form because everyone can get things done through mechatronics.
(In a short run scale, this is just everyone participating in society using the internet and virtual conferences in immersed reality)
In that outcome humanity would have a lot of free time to create and innovate and live a life of Philosophy and Science as the ancients like Socrates/Plato and others liked to proclaim.
It would be a field for a lot of innovative ideas, humans as a whole would not be very innovative at all times, but the accumulation of knowledge and information may lead to greater inventions.

New births and human reproduction would probally involve cloning, or are ovaries preserved and then utilized over time (aka no more periods).
The extension into areas such as entertainment would be interesting as well as how money in the sense works, if its developed to the point where most things can be created with a replicator (Star Trek) then credits would be used rarely. (Pure energy) converted into matter is convinient enough that money would rarely be needed for anything.
By then we would be nearing a Tier 4 to Tier 5 civilization so that's a bit far out. Might need to define a timeline in the OP as to how far out into the future you were thinking.
Too far in the future and we get into a whole new set of fun

Humanity discovers Alien races on other planets and were entering into a Holy War with them

Politics is needed again we had a good run
As far as I can see it, where we are now in human evolution is envisioning the futures we cannot create yet at this point in time but in essence developing a framework of goals we can achieve in time for future generations.
(Hence Sci Fi etc get created)
If we become immortal and can make that science fiction a reality ourselves given enough time then things get much more interesting.
Also my Apologies if that one got a bit technical feel free to ask if you want additional referencing points.
