People don't understand how far along The Boring Company is
TBC's next major milestone is: continunous mining w/ zero-people in tunnel
I asked some of the team to rank this in SpaceX terms: Falcon 1, F9, F9 reusable, Starship, etc
Consensus was it's ~ as hard as the Falcon 9

This completes a 2.26 mile long Vegas Loop tunnel, connecting a property close to the Airport in the south to the Westgate Resort in the north. Along the way, there will be 8 new stations, including the Virgin Hotels and the Hughes Center.

Exceptionally hard engineering problem.
Also, this will be used to make Hyperloop a reality in the future.

xAI now has 460 MW of natural gas turbines installed and either operating or under construction. This includes 12 SMT-130 turbines at Colossus-1 and 7 Titan-350 turbines in Mississippi, located right across from Colossus-2. @elonmusk and @BrentM_SpaceX chose Mississippi due to

Still small fry at 1GW.
For serious power in the 100GW continuous range (~1/5 of USA average power consumption), it probably needs to be solar/battery powered.
At 1TW+, solar/battery is the only realistic option.

The rate at which you need to be updating or at least rethinking core parts of your architecture for AI agents is the most insane I’ve ever seen in tech.
The things you did to optimize for small context windows and non-reasoning models 1 year ago, to now what you do for large
Anish Acharya@illscience· 17 сент. 2025 г.The bitter lesson is coming for app gen and the best teams are already thinking about which investments are durable vs fleeting. More:
- Retention today is proportional to success rate - did the user get what they expected in a reasonable number of tokens (aesthetics / features

i've lived in the united states for most of the 42 years i've been alive, and i've never had people be openly racist to me.
until i heard from all the people either openly on X or privately in DMs hurling racist abuse at me for switching to the republican party.

Now seems highly probable that a new payment alternative emerges in the US (replacing credit/debit cards) on top of stablecoin rails. Just too damn efficient & cheap. Good riddance as they say! Who do you think is most likely to emerge as the new consumer payment app leader?

Boring Company is dangerously close to being able to provide every city dozens of miles of light rail/BRT type capacity with no public money, limited utilities interruption, and minimal new right-of-way. While offering passenger travel times that are a fraction of other transit.

I love trains, but the future is individualized mass transit with autonomous electric vehicles taking you precisely to your destination.
Tunnels are needed to address the fundamental choke points in cities. You can’t have 3D buildings and expect a 2D transport system to be effective! Multiple layers of tunnels enable transport to be 3D too.
The fastest way to travel long distances city center to city center, short of new physics, is cars/pods in vacuum tunnels.

Just a chance.
But I thought the probability was 0% for all prior Grok releases and now my neural net predicts ~10% probability and rising for Grok 5.
