Buildpacks has some nice features, at the expense of deviating from an industry standard (Dockerfiles). The speaker implies that Dockerfiles are fine if they're fine, but Buildpacks is attractive if you want more control over your Docker image build process.

Composite images. Don't need a Dockerfile for each app. Rebase layers when OS layer changes (Dockerfiles would require rebuilding the whole image).
