My main concern with Deno and Bun
But I won't write servers in Deno and put them to production in my own servers. (I don't like serverless)
You see, Deno(and Bun)'s business model is built around serverless (Deno deploy). And Deno deploy is ANOTHER runtime.
This means you're self hosting a version of Deno that's different from the majority of the Deno customer base.
Will the Deno open-source runtime receive the same love as Deno deploy runtime? even if Deno Deploy is the actual source of money? really?
How many people will use Deno to run servers on their own hardware? if that number is low, then I'd rather use Node.
P.S: Bun will probably be in the same boat (see https://oven.sh/). Deno already launched Deno deploy, so they're getting the attention here.
