Don't count on it. Have you ever seen how much time and effort has been put in making Firefox, Safari and Chrome compliant and performant? It'll take Ladybird ages to get anywhere near.

Someone could try to merge e,g, V8 and Servo, once that's in decent shape. But even then it'll be time consuming to build an acceptable UI, cookie and history management, plugin interface, etc.

And servo: I wish that one would get more mention as it's quite far along. Having multiple competing browsers again that are not controlled by megacorps would be great. Ladybird for browsing, Servo for embedding.
