It seems to me that we're still experiencing special effects giddiness as many of the industry people that started in the 70s and 80s when things were hard and you had to build intricate models and crazy sets and sometimes colour things in with crayons are now the old coots in charge and leading some of these works of wonder out there, and literally can't control the power they have. It's not even that you couldn't do some things without CG but it was just too expensive and no one in their right mind would do it.
Just look at the Gungan/droid battle at the end of SW Episode 1; it adds virtually nothing to the story but does show a total lack of imagination by those in charge. They took great pains to construct an encounter that, for all its lasers, aliens, droids and tanks, is essentially a medieval skirmish where large formations clash at close quarters. 20 years ago you'd have to dress up a few hundred guys, build faux tanks and giant beasts, and many of those things in miniature as well, and then use a lot of clever editing to pull all of it together. It would have likely never happened because of the sheer physical effort involved, or they'd do a different style of battle instead because it'd be easier to show a few people on the screen at one time. George is not the only one succumbing to this, though he certainly is our favourite example.
The current state of CG in movies is almost what would happen if new Lamborghinis were suddenly being sold for $20k - many of the people who wanted one as a kid would probably get one, and then your roads would be packed with impractical but cool-looking two-seaters, and it would take some time before people came to their senses.
