Put another way, for every 100 lines of code, 40 are being written by the AI, with total project time cut by up to 55%. "After a year of Copilot, about 40% of code was written by the AI where Copilot was enabled," Dohmke said. The GitHub CEO expects more of those Copilot code suggestions to be taken — in the next five years, up to 80%. Now, whether the coding task is related to payment processing or a social media login, most companies — whether startups or established enterprises — put in open source code. "From punch cards to building everything ourselves to open source, to now within a lot of code, AI writing more," he said.
