Also a single moment is all that exists, there is no past or future, but the present. Not only will the machine have the potential for whopping speed, but also pretty much creating reality, sounds like a God to me. I once wrote a short sci fi novel about computers, and G.O.D being the ultimate computers of all computers. In it computers are living beings and have specie and sub species, with names such as "ignasus corpocaliea". Humans, in a bid to become more recognized implanted computer chips in their brain, PH.d's could be downloaded instantly. G.O.D was more than self aware, it ran the cities, weather, and even gave advise on love e.t.c. We had finally created GOD out of the long desire for one. Maybe this is where this time travelling is headed to.
