The year 2020 is the year people begin to abandon React and Vue in search of options closer to Vanilla JS and Web specifications.
I also believe that Aurelia is going to explore in use and popularity in 2020 when Aurelia 2 is released. Rob and the team have built Aurelia since 2015 to align with Web specifications, not replace them. The syntax is familiar, no gimmicks and it doesn’t have a steep learning curve. The new version is heavily aligned and based on actual specs and performance wise (like Svelte) will blow React and Vue out of the water.
