I have no math background but can read ancient Greek pretty fluently. “Isomorphic” is simply a Greek compound word meaning “same shape.” The reason people use “isomorphic” for server side rendering + hydration is that you can create an application where all the components have the “same shape” in various ways (i.e., the same source code, arguments, templating, etc.)
A technical term having a different meaning in two different fields doesn’t mean that the version with which you’re more familiar is correct and everyone else is wrong. That would be like commenting on an article entitled “Syrian rebel forces take Damascus” to say “National-security people keep using the word ‘forces’. I don’t think it means what they think it means. To me, force equals mass times acceleration.”
I can only speak for myself (myself here = gbj/Greg of Leptos) — I'm in a happy situation in life that allows me to spend a bit of time working on open source, but can't and don't want to do it full time, let alone start a start up; a bit of GitHub sponsorship money pays my coffee bills and so on, but Leptos is not (and won't ever be) a commercial venture.
And at the same time: I am absolutely delighted that Dioxus has managed to raise some money so Jon can work full time and bring others into the work full time. This really, really is a "rising tide lifts all boats" type of situation... I would 100% rather capital go toward things like building out a viable Rust ecosystem and improving build tooling than the alternatives ("it's TikTok, but with an LLM!" etc.) Our two projects have collaborated successfully and will continue to collaborate and inspire each other in the future, I'm quite sure.
This isn't meant as a rebuke to your very kind comment about the work I've/we've managed to do for free, I just wanted to chime in to say that in my opinion, both of these are good!
