SpaceX’s Starlink internet constellation deemed ‘a license to print money’
According to a draft paper written by networking researcher and professor Mark Handley, SpaceX’s Starlink internet satellite constellation has the potential to significantly disrupt the global networking economy and infrastructure and do so with as little as a third of the initial proposal’s 4425 satellites in orbit.
A step or so further, Dr. Handley (according to a University College London colleague) suspects that a network like that proposed by SpaceX could rapidly become “a license to print money” thanks to the tangible benefits it would provide financial institutions and banks – as of today, shaving mere milliseconds off of communications latency can be a serious competitive advantage for traders.

Asked to condense his argument into a few sentences, Dr. Handley’s colleague (Reddit /u/davoloid) described his excitement as such.
A Professor in Computer Science [Mark Handley] who specializes in how networks work has done a simulation of Starlink based on the available information. It will make long distance links very fast, as in, a short delay in sending a message, which we call latency. That’s very important to banks and similar companies, who always want to have the fastest information. They pay a lot of money to create networks, often private ones rather than through regular commercial providers. Even with the first phase of 1600 satellites, there will be big revenues for SpaceX.” – Reddit /u/davoloid, 11/2/18

Judging from the recent past of a practice known as High-Frequency Trading (HFT), where algorithms take over trading in financial markets and operate at speeds on the order of trades per millisecond, the highly volatile industry has already reached its conclusion. This is to say that HFT went from a wildly disruptive and lucrative technological advantage to a fundamental part of the world’s ever-changing financial infrastructure in just a few decades.
“The story about [HFT] is done. It’s a mature industry now, as much an embedded feature of our society as mutual funds or the income tax.” – Tim Worstall, 2017
“HFTs are still involved in the speed race and sometimes even race to pick off their market maker brethren. While it may be more expensive and more competitive today for HFT to pick off the slow traders, make no mistake, they have not gone away.” – Themis Trading, 2018
Much like electricity, the internet, and railroads went from kings of profit to marginal and tedious enterprises, it seems that HFT has gone from a nascent and fickle technology to a basic component of global infrastructure. As such, it is in no way, shape, or form “dead”. Just like step-change advancements in technology have forced service-based companies to upgrade or die, it seems that the availability of Starlink (or any comparable interconnected internet constellation) will create a massive imbalance between financial institutions that adopt early and those that do not or cannot.
If that ends up being the case, there will undoubtedly be an extraordinary surge in competitive financial infrastructure investment, with institutions desperately pursuing new ways to remain competitive (leveling the playing field vs. a shortcut to the front). Dr. Handley’s draft paper, accompanying video, and colleague’s clear excitement about the possibilities demonstrate (at least theoretically) that even just the first third (37%) of SpaceX’s preliminary 4425 satellite Starlink constellation would exhibit dramatic latency improvements between most conceivable access points.

The first step’s first step
With all 4425 satellites in place, the benefits approach or even surpass theoretical best-case statistics for literal straight-line fiber optic cables. Of course, SpaceX’s true proposal includes yet another 7520 very low Earth orbit (VLEO) Starlink satellites (~350 km) that would more than double the bandwidth available while potentially cutting another huge chunk out of the already unsurpassable latency performance of LEO Starlink (~1100-1300 km).
Of course, a massive amount of work remains before SpaceX before any of the above futures can or are even technically able to come to fruition. Aside from regulatory difficulties and concerns about space debris from a potential ~12,000+ new satellites, SpaceX will have to go one or even two magnitudes beyond what the status quo of satellite manufacturing believes is achievable, mass producing and launching satellites in volumes that will dwarf anything undertaken in the history of spaceflight. Still, if anyone is going to accomplish such an extraordinary feat, one would be hard-pressed to find a better bet than SpaceX.

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
Investor's Corner
Tesla’s flying Roadster just revealed something bigger than the car
Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.
The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.
Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.
The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.
The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.
Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.
The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.
Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.
