Plowing familiar ground

Back when Star Trek-Next Gen was on, there was a specific point where the series went off the rails - it was when the writers created the Borg. Here was a race that was too powerful, that basicaly could not be defeated. It took the writers a lot of bad scripts to write their way our of that paper bag. Well, I'm starting to think that the writers for Stargate-SG-1 have created the same problem for themselves with the replicators. The disruptor weapons that Carter and the Asgard came up with don't work - the replicators adapt immediately - hmm, just like the Borg did to phasers. The Goa'uld are busy getting their collective butts hammered, and there doesn't seem to be any way out other than a miracle weapon of the ancients. It's sounding familiar, and not in a good way.
