We dialog with young edtech entrepreneur Danish Dhamani, whose Philly-based start-up, Orai (‘Oral’ + ‘AI’), offers a speech coach on your cell. Dhamani, a graduate in Mechanical Engineering from Drexel University, tells us about how he built a business out of his own fear of public speaking before he goes on to tell us it’s like to have done a TED talk that’s had over a million views, the benefits of tech incubators, and other topics that include his personal journey from Pakistan to Philadelphia via Tanzania - and from Mechanical Engineer to Speech Coach; why speaking well in public is very far from being a ‘soft’ skill; why developers sit in different kinds of office spaces now; how saying ‘um’ can lose you a life (as it were!); more on that biggie, the problem of bias in AI; and the precise percentage of smile-degree you need to optimize for.
