My college dorm project just broke the world speed record.
Reaper hit 790 km/h (491 mph) carrying a 1.2 kg (2.6 lb) payload.
These 3 Reapers are now the world’s fastest small jet-powered drones.
Each of them can hold that speed for 4 minutes on a full tank.
Reaper can be rail- or truck-launched, climb to 2,000 m (6,600 ft) in under 20 seconds, then fly for 50 km (31 mi) at full speed.
This is now a reliable and repeatable system. Future testing and small optimizations should push the top speed past 800 km/h (500 mph).

Thoughts on $AMZN
$AMZN reported but I won’t bore you with another recap of the quarterly results. A hundred other people have already done that, and repeating the same numbers. Instead, I rather focus on a few things that caught my attention.
$AMZN p added $13 billion in quarterly AWS revenue, that’s equivalent to $50 billion in annual revenue. To put that into perspective, AWS is adding the equivalent of an enormous technology company to its revenue base every year, while operating margins approaching 39%. That’s an extraordinary accomplishment for a business already operating at this scale.
Management expects AWS revenue growth to exceed 40% in both 2027 and 2028, which is a remarkable outlook for a business of this magnitude. We’re not talking about a startup doubling from $100 million to $200 million in revenue, but one of the world’s largest cloud businesses compounding at rates normally associated with much smaller companies. The absolute dollars involved are staggering, and I think it’s worth exploring what those numbers might eventually mean for $AMZN’s earning power.
Let’s do some destination analysis, because this is where things become fascinating. Suppose AWS eventually reaches $180 billion in annual revenue and subsequently grows 40% for two consecutive years. Revenue would reach approximately $252 billion after the first year and $353 billion after the second. At a hypothetical 35% operating margin, AWS alone would generate $124 billion in annual operating income.
For perspective, $AMZN’s entire business currently generates approximately $104 billion in operating income. In other words, under those assumptions, AWS alone could eventually produce more operating profit than all of $AMZN generates today. That’s a remarkable possibility, although the $180 billion starting point and 35% margin are assumptions. Nevertheless, it gives you some appreciation for the enormous earnings potential.
But here’s where my enthusiasm becomes considerably more measured, because revenue growth and shareholder value creation are two entirely different things. $AMZN generated $168 billion in operating cash flow over the past twelve months, an extraordinary amount of money by almost any standard. Unfortunately, it also spent approximately $211 billion on capital expenditures, resulting in negative $42 billion of free cash flow. During the most recent quarter alone, capital spending approached $76 billion, while management expects approximately $220 billion in cash capital expenditures next year.
Now, I have absolutely no problem with a company sacrificing current free cash flow to create substantially greater future earning power (ie $MELI). In fact, some of my most successful investments have involved businesses that deliberately prioritized long term opportunities over short term profitability. But calling something an investment doesn’t automatically make it a good investment, and spending enormous amounts of money doesn’t establish that those expenditures will generate attractive returns. What matters is the relationship between the capital invested and the incremental economic value created.
Consider the economics of AI infrastructure, because I think this is one of the most important questions facing $AMZN today. A data center building might remain economically productive for decades, but the computing equipment inside it could become obsolete much faster. If $AMZN spends $100 billion expanding capacity, how much of that spending creates durable earning power, and how much will eventually need to be repeated simply to maintain its competitive position? The difference between growth CAPEX and recurring maintenance could have enormous implications for future free cash flow. On a side note, it’s quite fashionable at the moment to ignore this truism.

Amazon largest dollar spend on CAPEX, slowest Y/Y rate.
BUT $42B incremental.

Anthropic S-1:
--over 11,900 customers pay $100K+ a year, up from about 950 a year earlier.
--over $130B cash. (likely over $200B post IPO)

elon popping the AI bubble after front running the Anthropic and OpenAI IPO is like watching an episode of billions and succession lol
Replying to @chamath
Pretty much.
As of the past few weeks, debt markets have almost entirely shut off access to money for any company that doesn’t have substantial revenue independent of AI data centers.
SpaceX closed $40B of debt for GPUs, but we’re investment grade and have Starlink & launch revenue.
That means the 200+ neoclouds are going to see guppy-level death and consolidation. Some will make it through, but not many.

Neoclouds that are able to lock in forward compute prices in derivatives markets will be able to get financing as long as they have a credible track record of execution.

Blackstone created an AI chief investment officer, which is trained on 14 years of the PE firm’s internal deal memos and debates.
Every potential new Blackstone investment requires reading of two memos now: a deal team memo and one from AI CIO (it doesn’t have a vote, though).

Vibe coded my parents' TV this afternoon!
It was showing a sponsored ad before you could even get to Netflix.
Gave Claude Code the model number, it found the TV on wifi, removed 25 Xiaomi packages and wrote a new launcher.
Looks like an Apple TV now lol

Tesla VP of Hardware Engineering Lars Moravy explains to Hagerty how the Roadster borrows SpaceX cold gas thrusters to make 0 to 60 possible in 0.55 seconds.
Truly insane:
▫️ 200L carbon-over wrapped pressure vessel
behind seat holds nitrogen at 10,000 PSI
▫️cold gas thrusters push out 80 kN of thrust (equivalent to a single fighter jet engine)
▫️Tesla went with nitrogen because “it just seemed wrong to put fuel into a car” (air is ~80% nitrogen, fair enough)
▫️thrusters same system satellites use to move in space (eg. the “psh psh psh" from Apollo 13 film)
▫️currently takes 6 to 7 hours to refill all nitrogen but Tesla working for it to be 30 minutes
▫️uses leg actuators from Optimus robot to manage downforce on wing
