I would definitely expect anything being manufactured now to be far more advanced that offerings from a decade ago at 2 to 3 times the price point. I doubt there was a production bike made 10-12 years ago that's as good as the Emonda ALR but that's not a statement I'm qualified to debate, so take it as just interweb opinion.
I would not expect these “advances” to have significant impacts on a frame’s longevity and ride quality. But I am happy to hear from people who are more informed on this.
By the way, I’m pretty sure that Hydroformed aluminum frames have been around for at least 20 years or so.
