HN title is a little editorialized, making it sound like a new browser standard. Should be edited imo

The materials themselves also drip with exaggeration and hand-waving, talking about things like "the legacy cloud VM" (emphasis mine), "unmatched security", "spinning up the entire dev environment in milliseconds"

All of this is aside from the actual technology, which could be cool, I have no idea yet. But it rubbed me the wrong way

They are aiming to develop a standard... of sorts...
