volume is discrete: made of a finite integer number of Planck cubes (each the Planck length cubed, ~10⁻¹⁰⁵ m³). Space isn’t continuous; at the smallest scale it’s quantized like voxels in a simulation. Irrational numbers (like unlimited digits of π) have no physical basis be

BREAKING: SpaceXAI has released a major new update for Grok Build (v1.0.13).
The update improves reliability with automatic retries and recovery from truncated responses, inference failures, oversized images and session-saving issues.
It also adds smarter hooks, better Windows support, faster MCP and session startup, improved scheduled tasks and quicker compressed CLI downloads.
Features
• Length-truncated responses now continue automatically instead of failing the turn.
• Hooks can now ask the user to confirm a tool call instead of always allowing or denying.
• Hooks can now request deferral or add context shown to the model after a tool runs.
• Session close now records detailed timing data for performance analysis.
• Credit limit upsell now offers a Try Again button to retry the last prompt.
• Pasted images now show a live pixel preview in the prompt box on iTerm2.
Bug Fixes
• Transient inference failures (stalls, drops, 5xx) now retry automatically instead of ending the turn.
• Windows users can now correctly open ~/.grok and worktree sessions.
• Session data is now more reliably saved after prompts and on power loss.
• Compaction failures now show the actual error instead of a generic message.
• Truncation error messages now show the right guidance instead of suggesting an unhelpful retry.
• Truncated tool calls are now executed instead of failing the turn when arguments are complete.
• Images larger than 2000px no longer brick sessions on many-image requests.
• Wrapped hyperlinks in the pager now remain fully clickable on Windows Terminal instead of only the first line.
• Recurring scheduled tasks now include a reminder to stop the monitor when work finishes.
• Scheduled task IDs are now full UUID strings, preventing collisions when tasks are created in the same millisecond.
Performance
• Subagent spawning is faster when connections drop during bursts.
• Session startup with MCP servers is now much faster when auth is already configured.
• MCP server startup no longer stalls behind a fixed batch size.
• CLI downloads are now compressed, making fresh installs and updates substantially faster.

It’s a function of SF Bay Area political views.
Grok is California plus Texas, so more centered.

And the roads, cities, factories and entire civilization built there all trace back to this machine

Elon Musk was asked how he handles employees who disagree with him publicly.
His answer contradicts every leadership book written in the last 30 years.
"I'd rather have someone who argues with me and is right than someone who agrees with me and is wrong."
The room expected the diplomatic answer. That he values diverse perspectives. That healthy debate makes the team stronger. The standard CEO answer about psychological safety.
He went further. He said the most dangerous person in any company is the one who agrees with you to protect their job. Because that person will let you drive the company off a cliff rather than risk being fired for telling you the cliff is there. The yes-man isn't loyal. He's selfish. He's trading the company's survival for his own comfort.
He said SpaceX has a rule. If an engineer sees a problem and doesn't speak up, and the problem later causes a failure, the silence is treated as more serious than the mistake itself. The person who made the error was trying. The person who watched the error and said nothing was protecting themselves at the cost of the mission.
Think about what that inverts. In most companies, the person who stays quiet and avoids conflict is rewarded with job security. At SpaceX, silence is the fireable offense and disagreement is the job requirement.
Most leaders say they want honesty. Then they punish the first person who delivers it. He built a system where dishonesty through silence is the thing that gets punished. The culture didn't happen by accident. It was engineered to make agreement more dangerous than disagreement.

When I try and explain that tokens inferenced increased 25-fold in a year and are multiplying exponentially, cascading through the economy, and are likely to push real GDP growth per year toward double digit territory, many clients and companies simply do not comprehend.
