The Redemption will come by the hands of the Four Craftsmen: Shem, Eliyahu, Moshiach ben Yosef, and Moshiach ben David. They are called Craftsmen due to their contributions in building the Third Temple. This building is very likely the craftsmanship in Light, as it is expected that the Messianic Temple will reach Earth and Zion from Shamayim.
The Prophecy of Ezekiel fits the description of the Building being of a "Craft" as the Nevuah is very specific in its measurements; It's construction is based on the diligence in its craft, and thus is it's revelation [to the World.]
When the Torah says that the World will be filled with Knowledge of God, is the Temple a sort of Spiritual Energy that will literally emanate Holiness into the World based on its design in conjunction with it's location on the Temple Mount; Thus "Tzion" makes this dynamic?
The Concept being described here is the same theory is that of the Pyramids all over the World; all functioning in the same way, implying that Man can harness Shefa (bring it down from Shamayim) by building on specific Lands. This would be Spiritual Technology going back to Shem and Pre-Flood, however what makes it Holy is when it is based on Tzedek (i.e. Third Temple consciousness) as Shem only had his merit based on Chesed and Tzedaka.
From the Time of Adam HaRishon, the World has a natural grid to it, flowing Raqiyah's (firmaments) which allow the World to be seen openly as a Creation of God; a microcosm of the Universe (much like the Temple.) This is true to the saying, "Man is a small World the World is a big Man.
When Holiness is on Earth, and Jerusalem is rebuilt, then Man can cultivate the World, into a vessel of Divine Shefa, making it a sort of Divine Technology, yet not from exploitation. The Jews in Egypt were this exploitation with their knowledge doubling as a tool with which they should build as well. Thus being in Eretz Yisrael and building the Temple is paramount to the World's restoration. With Torah influence, the Orlah can be removed from the World, which in Reality, this Orlah (over-growth) is technology of exploitation.
Ancient Egypt (with its Jewish influence to learn from) can be a message (albeit from exploitation) of how the World can radiate when built correctly, and perhaps this is an aspect of what the Third Temple will bring us, and bring the World.
Here is a 6-Part series describing the concept : "Ancient Technology"
I highly recommend watching all 6 videos if you have time; follow the links through the video by means of Youtube.
Is '72 the Year that balance is restored with a revival of Spirituality? The veil over our eyes couldnt be any thicker, so perhaps Hashem will circumcize our Hearts as predicted in the Navi.
