The other thing is that technology doesn't often mean what we think it does, like nerdy wonder weapons. The real tech advantage is the ability to create new things and adapt (or having already done so).

Like in the WWII Pacific we had no chance of getting close enough to Japan to even drop the nukes without the Proximity Fuse, which was a relatively low tech radar that exploded shells near targets so they didn't have to actually direct hit. Not a single kamikaze got through after we had those shells and then we controlled the sea.
