Finding Expertise in Search

Reading through this article I've discovered the following:

"Finding expertise has been a constant challenge, both outside and within organizations. Expertise has long been dependent on self-nomination and identification; however, these skills often aren't verifiable or have aged to the extent to which they're no longer relevant.

Available in Q1 CY20 as preview, in Microsoft Search you’ll be able discover instant answers for people results based on their skill matches. Answers are high confidence results that satisfy your intent directly, or help you navigate to your intended result(s) quickly. Answers can be either based on personal, organizational-wide or world content; they can be related to primary content from your current workload such as a file in SharePoint, or could introduce other content from outside of your current workload such as a personal flight answer based on Outlook content appearing in SharePoint."

What is the difference between this feature and the currently available feature in Delve for searching based on Skills, Education and Projects?
