I understand that the authors have very strong pedigree in their field, but given a lot of the motivation stems from regretted node design decisions, is the rust etc expertise on the project deep enough to not make equivalent mistakes that will be rued in another few years?

Genuine question (I assume it is, but presumably it was before with c++) - it just strikes me that once something becomes as successful as node, and given that nothing is ever perfect it might be useful to clarify why the technical insight might be better this time around - at least regarding the idioms of the underlying tech; the added experience at the architectural and implementation side a given.
