> Does this stack really put everything under the sun to shame?

Yes. I'm a .NET guy by trade and I've poked around Elixir/Phoenix a bit. I wish this stack (and its concepts) would gain some popularity in the enterprise so we could get rid of microservices and SPAs entirely. 99% of companies don't need Microservices, they solve problems they don't have at costs they shouldn't have to pay (velocity, complexity, etc.) SPAs could go away for most LOB apps with Phoenix Live, Blazor (.NET), or even just classic server-side web apps + Htmx.
