Here's another way of looking at that problem:
How many of those tools and technologies existed 1, 3, 5, 10 years ago?
Would you trust a six month-old tool on github to form the nucleus of your -- probably mundane, in the good way! -- project? Would you risk it all for the chance to have a slightly different way of rendering CSS or generating HTML?
... I didn't think so. React's been around for a long time now and it's got a lot of momentum and people who know it. So that's a pretty safe bet. Rinse and repeat.
Not all tools are critical and you do have some leeway. But when in doubt, pick something you can easily hire people to help you accomplish; that has been around a while; and that feels established.
