Was Copilot a largely riskless copycat effort because TabNine had previously proven the technology was feasible, TabNine had previously proven the business fit, and Copilot was backed by a gorilla of a company? Technology-wise, I have a Deep TabNine beta invitation email dated August 2019 and Wikipedia tells me that Copilot announced June 2021. Business-wise, Codata bought TabNine in December 2019. Gorilla-wise, TabNine was initially one lone undergraduate at Waterloo.
