These kind of articles usually have a summary buried in them, this might be it:
> "Lab-grown meat, dense cities, and nuclear energy need a rebrand. These need to be some of the new emblems of a sustainable path forward."
1) Lab-grown meat is nowhere near commercialization. At best we have plant-based meat substitutes that have similar nutritional profiles (high protein) to meat that can be produced at scale.
2) Dense cities don't really matter that much, as each human requires a similar amount of arable land to grow the food they need each year. That per-human land area might be a bit less for vegetarians, but I doubt it's that big of a factor.
3) Nuclear energy is still quite expensive relative to wind/solar/storage, and that won't change because nuclear's catastrophic failure potential requires over-engineering and high-security, plus the uranium ore and cooling water requirements can be problematic.
