I think Deno is a mistake at this point... Yes we thank Ryan Dahl for his huge contributions to integrating libuv and v8 outside of a browser to create node.js but a lot of work has been created by a huge ecosystem of developers after this. I think this de-facto fork of node.js will only serve to create fragmentation, and confuse product owners about which platform to use.
Sometimes splitting a community is worth it, but it shouldn't be a decision made lightly. And Ryan Dahl should consider his words bear weight as the original creator of the platform. I think it's a fair issue for critique.
