In a blog post published on September 24, he stated that many of these systems are run by private companies, using software and hardware that the public cannot review or understand.
Buterin emphasized that when technologies are controlled by a few organizations, they can become tools of control rather than progress. He pointed out that societies that have benefited most from new technologies were not just users, but creators of those technologies.

One major area of concern is healthcare. According to Buterin, private companies owning critical health technology can restrict who gets access to care, limit the sharing of important information, and raise privacy concerns. He praised efforts like PopVax, which take a more open approach to development and distribution.
Financial systems are also highlighted in his post. Buterin compared how quickly he was able to approve a cryptocurrency transaction with the time, money, and effort required to send a signed legal form abroad.
He sees digital wallets and blockchain tools as clear examples of how open systems can improve efficiency and lower barriers.

On September 20, Buterin shared his view on how Ethereum can build a strong financial foundation without straying from its values. What did he say? Read the full story.
