Remember that towards the end of the 90s, Netscape - the one promising new startup that threatened to break the Windows monopoly - had just had its ass handed to it by IE, with some spectacularly underhanded tactics. All the dot-coms had required hundreds of millions in funding and were rapidly blowing through them, with no sign of a profitable business model.
Hope didn't really return to techies until the mid-2000s, when a bunch of events (Google's IPO, acquisitions of Flickr & del.icio.us, development of Rails/Django/JQuery/MySQL, and founding of Facebook, Reddit, and YCombinator) made people realize "Hey, maybe it's not the end of history after all. People have actually been doing pretty cool stuff all this time when we weren't looking."
2015 seems like it was the new 2000. That'd put us around 2002-2003 right now, complete with the huge focus on P2P, security, and government overreach, and with a couple years to go before we realize that not everybody gave up.
What happened in the mid-2000s was that open-source software (and later Apple) finally broke Microsoft's hold on the route to the consumer, and suddenly small teams of people could deliver software that billions of people could use. There's a similar situation in R&D now; I remember that when I left Google 3 years ago, there was a whole lot of really cool stuff being developed that has yet to see the light of day. No corporation can hold innovation back forever though, because of Joy's Law: "No matter who you are, the majority of smart people do not work for you."
Mature industries, absent disruptive technology changes, tend to consolidate and be dominated.
Yes, Moore's law may seem to be slowing down right now, but all you need to do is look at the size, energy consumption, and ability of a human brain to realize that nature has blindly created a much more advanced "technology" than what we currently have.
Next, look at flying. Birds are nature's most advanced flying machines. We've been able to expand on that to the point where we have jets and even reusable rockets that can go a thousand times faster than the fastest bird.
Right now, computing is at the "man puts big flaps on his arms and jumps off high ledge" point. Once we figure out the "first airplane", AKA wright brothers moment, Moore's law will explode.
The internet titans of today will be replaced or be forced to change as the next wave of innovation takes over.
There may be a lull right now, but either AI or augmented reality looks like a good candidate for the next cycle.
