I think it's worth noting Marko's proven nature. In years of using eBay, have never had an issue with it. Sad that that's a high praise these days, but it is.

I think it's worth noting Marko's proven nature. In years of using eBay, have never had an issue with it. Sad that that's a high praise these days, but it is. eBay is fast, it works damn well, and always has. As a counter point, React's poster children, in messenger, Facebook and Instagram. Have all been plagued with UI bugs for the entire time I've used them. Obviously those aren't wholly comparable, but I do think it's worth taking note of the actual outcomes we have when tools are used at real scale.
