It's the year of Linux, haven't you heard? You may as well pack up your PC, study your favorite distro, and get ready to evangelize the open-source platform that will run on all systems in the future.

Joking aside, Linux has grown a bit in popularity and Microsoft continues to embrace it. While the tech giant has several apps and projects on Linux, Microsoft has not released an official Copilot app for Linux.

Sure, you could use Copilot on the web. Heck, you could even open up Microsoft Edge for Linux and install Copilot as a PWA (Progressive Web App). But where is the fun in that?

Instead, you could install the unofficial Copilot app for Linux built by Hayden Barnes. The app opens the Copilot web app in a dedicated GTK window and keeps your login session safely on disk. It also integrates with the desktop for autostart, system downloads, app launcher execution, and accessing hardware permissions like the microphone.

Barnes shared the project on X alongside a link to the app's GitHub page.

Many of the unofficial Copilot app's features overlap with using the web version of Copilot since Microsoft's AI tool is the center of the experience. But building the unofficial app as a native GTK application means its developer can deeply integrate system shortcuts, allow it to run quietly in the system tray, and trigger native OS notifications as opposed to relying on browser notifications.

Other benefits include native support for desktop accent colors and system dark themes. Overall, the app looks and feels far more natural on a Linux desktop than a standard browser window, and keeping Copilot isolated prevents it from slowing down if your main browser gets bogged down with dozens of open tabs.

The unofficial Copilot app for Linux is new, so we'll have to use it for a while to determine its long-term stability and performance. The first publicly available release of the app shipped this week.

We have a few systems running Linux spread across our team, so we'll let you know how the unofficial Copilot app performs over time.

Microsoft's stocks rallied this past week on accelerating AI growth, but the devil is always in the details.

Over the past month, Microsoft's shares have surged almost 30% following its quarterly filings, which beat Wall Street estimates by a significant margin. Microsoft proved that its AI business is accelerating in growth, and that cash flows remain healthy despite the firm's extensive capital expenditure on new data centers. However, new information suggests that there's still an enormous caveat to this news.

Analysis from Bloomberg has poured cold water over Microsoft's AI earnings potential. Disclosures from Microsoft suggest that OpenAI accounts for around 70% of Microsoft's total AI-related income, based on projected growth and previous disclosures that relate to revenue derived from OpenAI.

Microsoft reported that Copilot has millions of paid seats in Microsoft 365, and is being gradually adopted by a wide variety of governmental, public, and private sector businesses. But when you tally it against previous disclosures, it shows that GPU and infrastructure consumption specifically from OpenAI still drives between 65 to 70% of Microsoft's total AI business. Training platforms like ChatGPT and simply serving it to customers remains the cornerstone of Microsoft's AI business. That's potentially problematic and comes with a huge amount of risk.

On the gaming side, Call of Duty having an off year was enough to drive Xbox's total revenue down by 11%, leading to masses of layoffs. OpenAI, by comparison, is estimated to be losing anywhere between 10 and 20 billion dollars per year, on a comparatively modest $2-5 billion in revenue. OpenAI has a mountain of investors keeping it afloat right now, and Microsoft itself remains one of OpenAI's biggest backers, investing to the tune of billions in cash, infra, compute credits, and other instruments. On the face of it, Microsoft's AI bookings simply represent OpenAI's compute bill packaged as revenue.

It's not unheard of in business. Spotify ran losses for years until eventually becoming profitable (to the tune of billions, I might add). The idea is that you burn through debt, scale rapidly, change user behavior, and create new markets. Then, you lock people in and make them dependent, and start monetizing. Microsoft and OpenAI's other creditors are betting that one day, ChatGPT will become the default — an inescapable cornerstone of computing for billions of people.

But what if that doesn't happen?

What if people end up choosing Claude or Gemini over ChatGPT? What if regulatory scrutiny or public opinion sours ever further? What if elections are won on the promise of blocking new data centers, rather than enabling them?

The disclosures suggest that Microsoft's AI growth is inorganic and revolves almost entirely around training ChatGPT's models. If OpenAI imploded or decelerated, Microsoft would be on the hook for billions in sunk cost and enormous amounts of excess data center capacity.

There's no suggestion of a deceleration, quite the opposite — which is why the stock price has surged. But there's also little reason to believe that this entire segment is even vaguely organic.

Microsoft is already trying to diversify by training its own "more efficient" MAI models for consumer applications while boosting external enterprise adoption. It's started to devote more attention to its legacy consumer businesses too, namely Xbox and Windows, as neglect therein becomes untenable. But none of this will save Microsoft or its shareholders if the so-called "AI bubble" well and truly does pop.

It'll be interesting to watch how CEO Satya Nadella navigates Microsoft through this somewhat unprecedented era.
