Jensen on why fixing Energy in the UK is crucial:
“Without energy there’s no industry, without industry there’s no economic prosperity.
With no economic prosperity social problems are hard to fix, national security problems are hard to fix, everything is hard to fix.”
YES
He said we need to import it or create it here and it could be “fusion, fission, solar, hydro, whatever technology you want to use”
Jensen Huang on why the UK is in a great position in AI:
“The UK is in a Goldilocks moment.
You have every aspect necessary to take advantage of this new Industrial Revolution.
You just have to activate it”
He went on say how crucial fixing energy prices are in the UK if we want to take advantage of this moment.
US Federal excise tax is 24.4 cents per gallon. Suspending this would seem the fastest way to reduce diesel costs at the pump, in competitive markets anyway.

NON COMPETES BANNED
Today, the PM has announced that his Government will legislate to functionally ban non-compete agreements for startups and scaleups in the UK or as he called it - the Bosman ruling for ruling for the innovation sector' 😂
At the @StartupCltn been working on this for months and we think it’s a huge potential unlock for our tech ecosystem.
Here’s what you need to know…
- Measures to functionally ban non-competes for startups and scaleups in the UK are going to be set out.
- There will also be consultation on a wider set of restrictive practices including gardening leave.
- More detail on these plans at the budget in a few weeks (Wednesday 28th October) including a timetable for consultation with a view to legislation in the coming months.
We think this is a huge move and so do lots of friends including so many of the great founders that signed the letter with Inherent just the other week.
Why? Because talent matters and mobile talent means startups can build. The Valley was built on free-flowing talent. In the UK, we’re now seeing our own versions of this story with companies being built from alumni of both homegrown firms like Revolut and beyond. But we need that to move faster. Hiring and building faster means British startups and scaleups can grow faster. Barriers to that slow our ecosystem down.
We won’t pretend it will be perfect, and people (including some of our friends but also lots of fairly vested interests too) will have a right to disagree. But we think that startups will thrive and win in a faster paced Britain.
So we are delighted with the progress today - as part of a strong speech by the PM outlining his ambition for building the world’s leading innovation nation including more on tax, growing companies outside London and more. But this is the start, not the end of the process. The announcement launches a consultation. It doesn't mean the issue is settled. How far reform goes, and what it looks like on the ground, is still to be decided.
The Prime Minister today has done something that can materially impact the trajectory of the UK tech ecosystem and with it our economy - but only if we make sure it’s delivered. So, the real work starts now.
It is my understanding that there will be no math
"A spokesperson for OpenAI told Scientific American that the new model—which the company has not released to the public—produced almost every one of the results in response to a single prompt handed to a single AI agent."
That may be the most insane part of the entire story.
This wasn’t a giant swarm of agents grinding away for weeks. It was a single agent, given a single prompt, producing almost the entire set of results.

Plagueposting
🚨☣️More details on the Oct 1st pneumonic plague outbreak in Siberia, after a lab accident at a BSL-3 lab.
"FSB units accompanying ambulances transporting people who had been in contact with [lab tech] Shipilova for medical examination," as per local news. This is significant. FSB is Russia's domestic security / counterintelligence service, tasked w/implementing the national security of Russia." (Its predecessor was the KGB). This suggests quarantine was not voluntary.
It also means Russian authorities are treating the lab accident and plague outbreak as a national security issue, involving a lot more than routine public health.
“Pacing the frontier” is the new information campaign. Maybe “2 years to flatten the curve” was too on the nose.

We made history. On just our second flight, we became the first commercial space company from Europe to deliver satellites into orbit. Mission 'Onward and Upward' successfully lifted off and deployed payloads into orbit. A new chapter for European spaceflight. More: isaraerospace.com/press/hist…
