My point? Yeah, newer tube amps are WAY more reliable, but the new, higher end modeling stuff is moving things even farther forward!!
Since all a modeler can do is model/profile what already exists in real amps, I think it's a stretch to say that these devices move the bar forward.
It's a tool that's certainly a great convenience; it can be a money-saver, and it has its attractions, but I don't think a broader statement than that can be made.
Even the new ones like the Helix and the Kemper come up short in dynamic range, presence, and responsiveness to the controls on the guitar. As a result, I think they sound a bit two-dimensional, and don't mix well (I make my living in the studio, so that's pretty important). They're harder to do subtler things with, in my opinion. And they all have a degree of latency that, for me, requires a playing adjustment.
This isn't to say they're somehow bad, or not useful. They're just not for everyone.
On the other hand, for live shows I think they're very convenient. Light weight. Less cartage/shipping cost on a tour is a good thing. Bands spend a fortune shipping amps and cabs around the world. Great backup to have if you use a tube amp rig is another plus. Predictability, convenience, lots of sound choices -- all good things.
But not a replacement for tube amps, more of an alternative.
