We will have two “machines” that can quite literally do everything and they will be boring as tuck to us. These two will be the culmination of 100s of other advances though.

One will be able to capture all information in an area (as time goes that area size increases) meaning all atoms and their bonds and where they are in relation to a fixed point. This is no small feat and we could probably only do something like this in a VERY small area right now. That capture goes for is too obviously.

Two: Use nanotechnology to put those that same configuration together. Also with variations if needed meaning you live forever and retain your memories. You can teleport, we can even time travel back to previous stored instances where needed and practical. A boring form of time travel but it is time travel nonetheless.
