SharePoint: From Concept to Creation to Impact + Live AMA

SharePoint has a lot of content, ranging from Lists, Pages and Documents.
Searching & presenting corporate content tailored to the company information structure & policies is done mostly through SPO Search. I have the following questions :
1. Do you see SPO Agents as an enhancement / replacement for SPO Search ?
2. Are you planning to open access to the Semantic Index or offer extensive customize, for example with the SPFx Framework, to developer, so they can build custom content search & presentation solutions ?

Thanks for hosting the AMA !
