except that if deno fails because its uptake cost makes it hard for engineers to sell to their org, what does it accomplish then? At least if it's getting used heavily people can invest engineering effort into the ecosystem on company time.
But I think one of Deno’s initial appeals was “A JS/TS runtime for people that don’t want to deal with JavaScript status quo”. Its accomplishment would have been to be bold and try something different, similar to for example Zig.
