Google’s ChatGPT competitor, Bard, is currently available in around 180 countries including the UK, the US, Mexico, and Japan. However, while the few dozen people living in the Pitcairn Islands can take advantage of this new technology, you can’t access it from Canada, China, or any of the 50+ countries in the European Union (at least, not without the help of a VPN).
The reasons for this remain unclear (except for China, where Google services are blocked by the country’s Great Firewall). However, Canada and the EU are each pushing their own laws aiming to regulate AI and protect individuals from bias, discrimination, or other risks that could stem from lax oversight in the sector.
