Never heard of that one but I’m not surprised that others will take advantage of this opportunity. If Aurelia ever gets a ‘In Action’ book from manning then I’d definitely check it out.
Since there is no upgrade path, I believe Angular community will lose trust on next major iteration… Who’s to say that it’s not backward compatible or no upgrade path? As a technical enthusiasts, I wouldn’t care that much as long as it’s fun to use it. From business perspective… it looks pretty horrible ROI. I think it would be hard to convince to use Angular 2 to upper management…
