1/ why Quantum is BULLSHIT

"paving a path towards potential future"

like saying: 'Working towards possibility of maybe a thing that might one day be a breakthrough if a breakthrough were to maybe occur'

Here I assemble just 2005 to 2015 annual headlines or this BULLSHIT 2/ I could start in the 90s. But let's just go thru 20yrs of BULLSHIT

2/ THE BIG IDEA?

Your brain has a direct hotline to your immune system.

Specific neurons in the vagus nerve detect inflammatory signals + then tell your brainstem to dial inflammation up or down.

When our team cut this connection immune responses went completely haywire!

1/ Apple researchers just dropped NEW foundation model on BEHAVIORAL data from wearables.

1/ Beyond the hype + headlines

some eye-opening AI stats to consider

Today Mag 7 = 35% of US stock mkt value

NVDA = 19% of that––and 42% of NVDA revenue comes from just 5 Big Tech co's buying GPUs:

Meta, Amazon, Microsoft, Google, Tesla 2/At recent lunch with LP who put Lux in business I talked about shift from consensus cloud inference (GPUs + datacenters + power) to on-device inference (memory + batteries)...

Apple just GaryMarcus'd LLM reasoning ability Image 2/ Apple tested today's "reasoning" AIs like Claude + DeepSeek which look smart—but when complexity rises, they collapse.

Not fail gracefully. Collapse completely.

BIG NEWS from Lux🚨…

American scientists––and those we attract to America🇺🇸––are what have helped make America not just great but absolutely + relatively EXCEPTIONAL.

We CANNOT cede scientific supremacy to China.
We don’t need talk, we need action… 2/ The 🇨🇳CCP “2035 Science & Technology Vision” states unapologetically “original innovation is the sharpest blade.” coupling that declaration w/ vast subsidies, talent visas + procurement guarantees which have helped them take lead in 37 of 44 critical and emerging technologies!

1/ My take on Trump in exchange with one of my smartest market friends.

Bizarrely I’m more sanguine.

Either it’s the greatest policy mistake and blunder of a rollout ever. OR it ends up with some grand bargain for those that want to ensure certainty and stability by doing long term deals or otherwise face massive undulating volatility in his flip-flopping, fickle whims.

I think overall across all domains (tech cos, universities, law firms, countries) they got very confident and then cocky ... I think it started with the Silicon Valley and Elon flip over… And then Zuck shifting his board and taking a knee… And he saw powerful person after powerful person pledging fealty out of fear. I think that further emboldened them the "we’re fucking here We are in total control. We have all the leverage. You do what we say or you're fucked" from big tech to Zelensky to law firms to Columbia + Harvard and then the rest of the world

And Whether it’s the market fighting back or law firms, fighting back or universities fighting back… He’s gotta double down and not show weakness or concede. He was wrong… It’s very tough game theory.

The other view… Is they try a few experiments mindful that it could create chaos… And going into midterms they stabilized with more predictability market so and they have total political control 2/ post election when all Trump bros were “golden age of America” with 80s topgun hulk hogan f-yeah amurica hype videos…

We bought deep out of the money puts

Because the consensus and stability were the consensus view and the scarce contrarian view was: insane volatility ahead

1/ an urgent wake-up call ⏰

A new bombshell report just dropped.

China’s playbook isn’t war in the open—it’s war in the seams.

They target the gaps between state & federal, public & private, markets & security.

America must 'armor up' 🧵... 2/ The CCP’s strategy?

Hollow out U.S. strength from within.

Critical infrastructure? Infiltrated.
Universities? Compromised.
State pension funds? Financing China’s military tech.

1/ QATAR -

If you were fly on wall in Qatar's strategy meetings you’d hear their not so secret strategy

i) keep up economic relations w/Iran (esp w shared gas reserves)

ii) support Islamist groups (esp Muslim Brotherhood) + use the masses as pawns for political leverage.. 2/

iii) assert distinct identity in MidEast geopolitics as a ‘mediator’

iv) religious mafia style––foment fervent believers (funding Al Jazeera propoganda + mosques/ Imams to rule over other country populations) grow geopolitical power depsite tiny size (and no real military)

1/ 🏦 America needs an experienced wise and smarter than other global finance heads so he can outsmart them––a Treasury Secretary who puts 🇺🇸 first.

A leader who gets tariffs, trade, & turning the tide back in our favor.

SCOTT BESSENT is definitely THAT guy.

Here’s why: 🧵 2/ Scott understands tariffs aren’t just a policy—they’re a POWER MOVE.

While others talk, Scott will make sure unfair trade practices PAY UP.

He’s about winning for American workers and businesses.

A quick high-level dive📡Image 2/ 🛰️ The Gulf War heralded stealth, precision, & GPS.

Some (first in history) news tomorrow… 2/ More than 3.5 billion years ago, life on Earth emerged from chemical reactions.
