The taste to know what to build is what matters now.

Because cheap prototyping creates many variants, a curation process must filter and amplify the few that matter, otherwise noise buries the value created by individual experiments.

If many implementations and media are possible, choosing the right format becomes the key lever, because format shapes how the message is understood and whether people act on it.

When building is easy and teams feel pressure to show progress, engineers often produce lots of documents as visible output, which causes many documents to exist that do not actually communicate the key decisions.

Because tools let teams stand up features quickly and cheaply, there is a strong tendency to skip planning and jump straight to prototypes, which often pushes speed of execution ahead of clarity about the core problem.

Because building implementations has become cheap, the rare skill is 'taste' — picking the right problem and the right medium and presentation, since that choice decides which ideas actually reach people and create value.
