Supreme Court justices aren't 'the 9 greatest experts on the internet,' Elena Kagan said as they heard a major tech case

• The Supreme Court heard arguments in a high-profile tech challenge on Tuesday.
• The justices appeared skeptical about limiting Section 230 protections.
• Section 230 provides tech companies with legal immunity over the content shared on their sites.

The Supreme Court on Tuesday seemed hesitant to make sweeping changes to how the internet works as it reviewed a landmark federal law that protects tech companies from being sued over the content shared on their sites.

"We're a court," Justice Elena Kagan said during more than two-and-a-half hours of oral arguments on the major tech case. "We really don't know about these things. You know, these are not like the nine greatest experts on the internet."
