it has been underway for much longer and was built with people with actual browser engine experience
The key point is that Ladybird was developed by one person (not people) with some browser engine experience over a realtively short period, using only personal resources. While Andreas Kling worked on WebKit, his experience wasn't at the level of building an entire engine, which is evident from his videos. Experience alone isn't enough; he learned much of what he needed while developing Ladybird. While Andreas Kling is talented, many other developers on his team were equally skilled and yet he's the only WebKit developer I am aware of who built a browser on his own.
A task that not long ago was considered too hard to tackle, he proved it can be done even by people with relatively modest experience on building a browser.
It should be highlighted that Andreas main skills are his tremendous communication skills and the way he builds a mental model of the problem he's trying to solve, not his past WebKit experience (he wrote an entire OS, before building a browser for the OS he built, as a side project)
