Podcast Summary: "Signal’s Meredith Whittaker on Surveillance Capitalism, Text Privacy and AI"

On with Kara Swisher
Host: Kara Swisher | Guest: Meredith Whittaker, President of the Signal Foundation
Release Date: October 17, 2024

1. Introduction

In this episode of On with Kara Swisher, Kara engages in an in-depth conversation with Meredith Whittaker, the president of the Signal Foundation. Whittaker, renowned for her advocacy in data privacy and her pivotal role in founding the AI Now Institute, discusses the intersection of surveillance capitalism, text privacy, and the burgeoning AI economy.

2. Meredith Whittaker's Background

Whittaker begins by recounting her extensive career in tech, highlighting her tenure at Google from 2006 to 2019. During her time at Google, she founded Google Open Research and the Measurement Lab (MLAB) in 2017. Additionally, she co-founded the AI Now Institute at NYU with Kate Crawford to explore the social implications of AI.

Meredith Whittaker [04:56]: "How do we build technology that is actually beneficial, actually rights-preserving? How do we stop the bad stuff, start the good stuff?"

3. Transition to the Signal Foundation

Whittaker discusses her departure from Google, citing increasing hostility from management due to her advocacy for ethical business practices and data privacy. Feeling the need for change after 13 years and enduring pressure to curb her activism, she transitioned to the Signal Foundation, viewing it as a fulfillment of her lifelong mission to promote data privacy.

Meredith Whittaker [06:06]: "I had raised a lot of alarms. I'd participated in organizing against some really troubling business decisions... my adrenals needed a rest, I needed a change of pace."

4. Signal Messenger's Privacy Features

Whittaker delves into what sets Signal apart from other messaging apps. Signal employs its proprietary Signal Protocol, considered the gold standard in end-to-end encryption, ensuring that not only the content of messages but also metadata remains private. Unlike competitors like WhatsApp, Signal collects minimal user data, making it a preferred choice for privacy-conscious users, journalists, and human rights workers.

Meredith Whittaker [14:20]: "Signal's big difference is that we are truly private. We collect as close to no data as possible and we develop open source so that our claims, our code, our privacy guarantees don't have to be taken on trust."

5. Funding and Sustainability of Signal

Operating as a nonprofit, Signal relies primarily on donations, including substantial support from Brian Acton, the co-founder of WhatsApp. Whittaker emphasizes the challenges of sustaining a privacy-focused platform without resorting to invasive business models. The foundation explores various funding strategies, such as endowments, to ensure long-term viability without compromising its mission.

Meredith Whittaker [20:15]: "We are looking at different models right now for how we grow this. How do we sustain Signal, and how do we make sure that Signal isn't just a lonely pine tree growing in a desert."

6. Preparing for Quantum Computing (QDay)

Addressing future threats to encryption, Whittaker explains Signal's proactive measures against potential quantum computing attacks, a scenario dubbed "QDay." Signal has already implemented post-quantum-resistant encryption in its protocols to safeguard against "harvest now, read later" attacks, where encrypted data is stored and decrypted once quantum capabilities emerge.

Meredith Whittaker [22:54]: "Signal was the first private messenger to implement post-quantum resistance encryption for our Signal protocol."

7. Reputation and Security Claims

Whittaker responds to criticisms and misinformation regarding Signal's security. Specifically, she addresses Elon Musk's unfounded claims about vulnerabilities within Signal, clarifying that Signal has no credible reports of such issues. She underscores the importance of trust and transparency in maintaining Signal's reputation.

Meredith Whittaker [24:29]: "We have no credible reports of a known vulnerability in Signal. We have a security mailing list that we monitor assiduously where we haven't heard anything."

8. Legal and Regulatory Challenges

The conversation shifts to legislative efforts like the UK's Online Safety Act and the EU's Chat Control Bill, which aim to mandate message scanning to protect users, especially children. Whittaker vehemently opposes these measures, arguing that they compromise end-to-end encryption and overall network security by introducing backdoors.

Meredith Whittaker [30:35]: "Any backdoor in a network compromises the whole network. It's a critical vulnerability in the only core systems we have to guarantee confidentiality and cybersecurity of communications."

9. Impact of Telegram Founder’s Arrest

Whittaker differentiates Signal from platforms like Telegram, whose founder Pavel Durov faced legal issues related to content moderation failures. She highlights that Signal intentionally avoids features that facilitate large-scale broadcasts, thereby mitigating similar risks and legal obligations.

Meredith Whittaker [34:00]: "Signal is an interpersonal communications app. We intentionally do not add channels or features where you can go viral. That's just full stop."

10. Balancing Privacy and Safety

Addressing concerns around child sexual abuse materials (CSAM) and synthetic imagery, Whittaker emphasizes the need for comprehensive solutions beyond encryption. She advocates for robust social services and infrastructure to protect vulnerable individuals, critiquing the tendency to place the burden solely on encryption technologies.

Meredith Whittaker [36:21]: "There are many places to invest in actually tackling this, both online and offline. We need to look at the facts and address the root causes."

11. US State Bills on Age Verification

Whittaker critiques recent US state legislations requiring age verification for online access. She warns that such measures often lead to increased surveillance and tracking without effectively addressing the underlying issues of platform business models.

Meredith Whittaker [40:27]: "Age verification is a mass surveillance regime that is similar to tracking people's content and habits online. It doesn't work and it attacks the problem at the level of restriction, not business models."

12. The AI Economy and Surveillance Capitalism

Whittaker explores the consolidation of AI within big tech companies, noting that AI advancements are heavily dependent on vast data and computational resources controlled by a few giants like Microsoft, Google, Amazon, and Nvidia. She argues that this concentration perpetuates surveillance capitalism, where data collection drives profit and power.

Meredith Whittaker [51:56]: "AI is a product of big tech. They have the data, they have the compute, they have the access to market. It's not novel; it's an extension of established surveillance-driven business models."

13. Future of AI and Alternatives

Looking ahead, Whittaker envisions a future where the AI market undergoes significant culling, favoring smaller, purpose-built models over large, resource-intensive ones. She advocates for nonprofit AI research and development, emphasizing the need for models that prioritize societal benefits over profit.

Meredith Whittaker [56:43]: "There could be a model for AI research that is asking questions less useful to big players and more beneficial to society, like environmental monitoring."

14. Conclusion

In wrapping up, Whittaker underscores the importance of building an ecosystem that supports open technology and democratic governance. She calls for collective action to challenge toxic business models and foster innovative, privacy-centric alternatives.

Meredith Whittaker [66:01]: "How do we create a teeming ecosystem? How do we encourage open tech and democratic governance? These are the questions we need to answer to move forward."

Kara concludes by urging listeners to support platforms like Signal and stay informed about the critical issues surrounding data privacy and the AI economy.
