I tend to agree that LAMP will thrive for quite some time. But node.js and the article are interesting. The one thing I have witnessed with good success is returning tabular data as JSON and then using JavaScript to render the <table>. We used YUI for this with good results. We could easily return thousands of rows and then create tables that had real-time sorting, filtering and paging.
In general, JavaScript does seem like a reasonable choice at the server level (although I still prefer Python syntax). I'm still not a fan of some of the "event streaming". It definitely makes sense in some situations. But I still like most things to have an address.
