Deno feels like past the peak technology to me. You've got years and years of labor put into the Node.js ecosystem, and then the guy comes out with something that totally drops all of that for some gimmick features.

Could you not just build a URL loader and cache for importing in Node.js? Could sandboxing not just be a flag in Node.js? Do you really need TypeScript built in?

I'm not going to throw years of my and other's work away for some gimmicks. It's just a bad investment.
