Attention Is Memory-Bound, Not Compute-Bound
Everyone knows attention scales quadratically. Almost nobody talks about why that's a memory problem, not a math problem — and why it matters.
After the U.S. military agreement with OpenAI, millions of users have left the platform and deleted their accounts. This leads to only one thing: The Downfall of Open AI.

The era of “AI exceptionalism” is hitting a brutal reality check. For three years, OpenAI was the untouchable titan of the tech world, but as we move through 2026, the cracks are no longer just visible—they are structural. While the company recently grabbed headlines with a staggering $110 billion funding round at an $840 billion valuation, the underlying data suggests a "growth at all costs" strategy that may be reaching its breaking point.
Is OpenAI a tech revolutionary or just the most expensive experiment in history? Let’s look at the data.
The most alarming metric for OpenAI isn't their revenue, but their dominance—or lack thereof. In January 2025, ChatGPT held a commanding 87.2% of the AI chatbot market. By January 2026, that share had plummeted to 68%.
While OpenAI was busy perfecting "reasoning" models like o1, competitors moved in with surgical precision(For example: Google Gemini tripled its share to 18.2%, leveraging its 1-million-token context window and deep Android/Workspace integration).
OpenAI’s revenue growth is, quite literally, the fastest in corporate history. They hit a $20 billion revenue run rate in 2025, up from $6 billion in 2024. However, this isn't a traditional software success story.
The Data Point: OpenAI projects $345 billion in revenue between 2024 and 2029, but expects $488 billion in compute expenses alone.
The internal culture at 1801 Mission St. is reportedly fraying. In late 2025, CEO Sam Altman issued a "Code Red" memo, ordering a pivot away from experimental research (like the Sora video team and DALL-E) to focus entirely on ChatGPT’s speed and reliability.
When the people who built the "magic" leave to join the competition, the moat becomes a puddle.
OpenAI isn't "failing" in the traditional sense; it’s maturing. But the transition from a nimble research lab to a trillion-dollar commodity provider is fraught with peril. With shrinking market share, ballooning losses, and a talent drain, the "downfall" of ChatGPT isn't a collapse—it's the end of its era as the only player in the room.
The future of OpenAI is no longer about whether they can build the smartest AI. It’s about whether they can stop spending billions more than they make before the venture capital dries up.
