All my hopes are with Ladybird now
I follow Ladybird and appreciate their work. Especially implementing everything from standards, fixing standards and keeping it easy to follow the standards in code (and I'm proud Andreas is Swedish too).
But for something with the surface area of "everything you can do with a computer and it's uncle" a memory safe language feels like the right choice.
Just a knee-jerk opinion since I'm not a browser dev and existing sandboxing seems to work well enough, but an opinion nonetheless.
I think in swift like C# and Microsoft. Yeah, you can and I do run a lot of C# code in other platforms. But if you really wanna use everything it has to offer, it needs to be in windows, at least in the development stages.
