That's an "I don't know if Webpack will be a popular choice for greenfield projects in 5 years" (which is stating the obvious and should be equally true for Vite or turbopack at this point and very far from what you wrote).
Culture difference behind the misinterpretation maybe? The lack of self-inflation, exaggerated confidence and exceptionalism we might expect from Americanized presenters shouldn't be taken for insecurity or doubt ;)
I'd listen to what they say at face-value rather than trying to read the lines applying the wrong lens.
> Regarding TurboPack, we'll see. So far it's not very popular outside of Next.
It's very early still, in alpha, and isn't recommended for production use outside of Next, where most of the focus on integration and tooling has been so far AFAIK.
