React got popular due to the virtual document object model (DOM) which enables it to enhance performance of web apps and PWA significantly. Usage of Virtual DOM allows efficient rendering where only certain part of webpage is rerendered speeding up performance. Absence of Virtual DOM results in less memory intensive applications.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. It was a great privilege.
