When things are open source, people have equal access - and when people have equal access, everyone benefits.

"I believe that open source is necessary for a positive AI future. AI has more potential than any other modern technology to increase human productivity, creativity, and quality of life – and to accelerate economic growth while unlocking progress in medical and scientific research. Open source will ensure…that power isn’t concentrated in the hands of a small number of companies, and that the technology can be deployed more evenly and safely across society."

– Mark Zuckerberg, Founder and CEO at Meta
