happy to see another fan of aurelia here.
i actually started with angular 1 before it became popular. i evaluated the alternatives at the time, knockout, ember and a few others, and angularjs just looked the best. finally when angular 1 was no longer maintained i discovered aurelia, in part because rob eisenberg had an interesting story about how he got invited to the angular team because of his ideas, and how he left again because he could not actually get his ideas implemented.
it's a bit disappointing that development of aurelia 2 is slow going, but in some ways i consider that a good thing, considering how fast vue and svelte are evolving away from what they were originally.
i need to look at solid.js though. the only promising newcomer in resent years if the state of js survey is any indication.
