Well, I suppose it is if you define the total amount of wealth in, say the US, as the number of gold bars sitting in Fort Knox.
But for more sensible definitions, technological advancement can most certainly increase wealth. For example, advances in manufacturing technology could diminish the number of Rubik's cubes that have to be discarded due to defect, thus strictly increasing the number of Rubik's cubes in the world. Since a finished Rubik's cube has more value than a discarded heap of plastic and colored stickers, increases in the efficiency of Rubik's cube manufacturing mean a strict increase in the amount of wealth available in the world!

But, hey...only theb people who own the resourses see any benefit from that. Me and you might save a dollar on one, but the guy making them makes millions extra.
