The underlying commercialization of the Web is too lucrative to be gone in 5 years, it's just a question of what watering holes the non-dead congregate at, and how the predators target them.

At this point, I'd expect a further move towards walled gardens to reduce competition (harder to scrape, copy, etc.) and increase the barrier for entry to new players: it's going to be even more pay to play than it is now.

I don't expect the Web to die, websites will stay a thing, but how they are discovered and used will undoubtedly shift. E.g., relying on tricks to get search traffic is a waste of time if nobody uses search.

Hopeful take: other protocols take more prominence. Disruptions and a fracture or two might help the Internet stay useful.
