Does knowledge represent technology?
No if you look at the whole verse you see it was the tree of knowledge of good and evil.
Gen 2:9 And out of the ground made the LORD God to grow every tree that is pleasant to the sight, and good for food; the tree of life also in the midst of the garden, and the
tree of knowledge of good and evil.So it wasn't just technology and it wasn't knwoledge at all really - it was the ability to tell the difference between good and evil. This ability together with our free will makes it possible to sin, because it allows us to have intent to go with our actions, and this intent can be to have our wills in accordance with God's or not.
