The NYT is suing OpenAI + Microsoft for its alleged use of millions of NYT copyright articles in training.

AI has clearly increased the stakes of data flows on the internet.

Previously scraping and other data sourcing was relatively low scale, only powering sophisticated buyers in infrequent deals.

Now, of course, there's real opportunity cost for letting your data be used by others in a way you do not intend.

Interestingly, this coincides with the coming demise of cookies, rising tide of state privacy laws, and Apple's new anti-fingerprinting Privacy Manifests for iOS.

This Scrape The Internet strategy is perhaps a final form of
> You Are The Product
and clearly, many folks are not happy about it.

Excited to see a 2024 of maturing (and more expressive!) data flows on the internet...

🚀 AI's Trillion-Dollar Frontier: Who Will Dominate? 🌟

During my research, I came across at the "100 Most Promising A.I. Startups Globally" infographic.

ByteDance and UBTECH Robotics and more. Cancer, Healthcare, Finance and Insurance, Mobility with autonomous vehicles- every sector has some "to become" next Unicorn.

But let's not overlook the titans shaping the AI revolution. The race to become the next trillion-dollar giants is on, and AI is the fuel powering the tech giants.

🔝 Today's AI Titans:
Apple leads with a colossal $3.02T market cap.
Microsoft follows closely at $2.79T, innovating with AI in enterprise and consumer spaces.
Google (Alphabet) at $1.78T, continues to push the envelope with projects like Imagen Video.
Amazon stands at $1.59T, integrating AI across AWS and consumer products.
NVIDIA, the brain behind AI computing, is at $1.21T.

📈 Rising Stars:
Meta for Business once over the trillion mark, now at $907B, is making waves with OSS AI projects.

Adobe, valued at $273B, is redefining creativity with AI-driven tools.

OpenAI and Anthropic, valued around $29B and $30B (or $90bn recently) respectively, are the dark horses in the AI race.

🔍 Beyond the Giants:
Dataiku, Frame AI, Neatsy, Inc, SoundHound AI, Moveworks, and Systematic are the startups to watch, each carving out their niche in the AI ecosystem.

The AI landscape is vast and growing, with Microsoft, Google, and Amazon NVIDIA and Apple poised to lead.

🔥This concentration of power raises ethical concerns, risks creating monopolies, and could limit the diversity of thought and creativity that is so vital for the advancement of AI. As we celebrate the achievements of these promising startups, we must also remain vigilant about the challenges posed by big tech's outsized influence in the AI space.

🤔 Who do you think will hit the trillion-dollar mark next? What AI trends will redefine our future? Share your bets and join the conversation on the next wave of AI dominance!
