One interesting bit at the end (last 15mins I think), was talking about the history of UE, where from UE3 -> UE4, they dropped support for their initial attempt at an Unreal scripting language (UnrealScript?) in favour of C++/Blueprint, because it was just one person working on the language. But with the success of Fortnite, they could build a world class team to work on a new language that can be more future-proof for the metaverse. Don’t have enough programming language design expertise to tell whether the decisions they are making are good or not, but very curious how it’ll all turn out.
