Goa'uld Technology

[wise one]

jaffa are busy training and fighting wars and worshipping false gods, they wouldnt have time to eat with thier family cos they are busy holding sticks in corridors

So, going over various Stargate Episodes, of which we've seen Jaffa Planets, or even where we've been on the home planet of a Goa'uld, we never seem to see any signs of advanced structures or tech etc.

You mean Goauld cities not unlike Earth right? Well no SG unit has actually been on a Goauld Homeworld only Military fortresses and outposts. I mean most of the worlds SG teams have been to were only one outpost structure near the gate.

We have seen glimpse of them on a few occassions. We have seen a picture of Yu's Palace and his forbidden City in season 5 The Summit. We have also seen Sokar's Homeworld in The Devil you know. He had two Pyramids etc.
