Actually I would say that was the turning point when the web started to become the dominant platform. Not the conclusion.

Before then it was Flash and native apps. Before then, smart phones weren’t common (eg the iPhone was just over a year old at that point) and the common idiom was to write native apps for Windows Mobile.

IE was still the dominant browser too, Firefox and WebKit were only starting to take over but we are still a long way from IE being displaced.

Electron didn’t exist so desktop app were still native and thus Linux was still a second class citizen.

It took roughly another roughly 2015 before the web because the dominant platform. But by 2005 you could already see the times were changing. It just took ages for technology to catch up. The advent of v8 and thus node and Electron, for that transition to “complete”.

> It wasn't until 2009 with the introduction of Node.js that JavaScript became a viable option for backend development.

JavaScript was used for backend development since the late 1990s via the Rhino engine (the backends wouldn't be pure JS generally but a mix of JS and Java; Rhino was a JS engine for the JVM with Java interop as a key feature.)
