Claim

Apple's new lawsuit against OpenAI over trade secrets looks like more smoke than fire.

Ben Thompson's analysis, relayed by Andrew Sharp, concludes that Apple's trade-secrets lawsuit against OpenAI is largely overblown rather than a sign of a deep underlying issue.

transcript

Ben Thompson: In Monday's Update Ben parsed a new lawsuit from Apple that looks like more smoke than fire, and in Tuesday's Update he doubled back to cover the revamped ChatGPT app on the Mac and what it signals about the company's priorities going forward.

Claim◆

IBM's mainframe sales losses will never come back, because AI can now port the essential backend programs that run on archaic mainframe technology.

Ben Thompson argues that IBM's worst-ever stock day reflects investor fear that AI can finally migrate legacy mainframe software off IBM's platforms for good, not just a temporary dip from AI capex distraction.

transcript

Ben Thompson: mainframes defined the first wave of IT, and they are so useful and essential that IBM's customer base is largely the same as it was half a century ago. Now, however, mainframe sales and the software that runs on them are faltering; management blamed AI spend, but as I argued in Wednesday's Update, the real concern for IBM is that AI's ability to port the essential backend programs that run on archaic technology will mean those missed sales never come back.

Context

IBM's preliminary results spooked the software market generally, but the real story is specifically about IBM and its own mainframe franchise, not the broader software industry.

Ben Thompson frames IBM's market-rattling preliminary results as a narrow story about IBM's mainframe franchise specifically, despite the broader software-market selloff it triggered.

transcript

Ben Thompson: IBM Misses, IBM's Mainframe Moat, IBM's Many AI Problems — IBM announced preliminary results that spooked the software market generally; this is a story, however, specifically about IBM and its mainframe franchise.

Claim◆

Netflix's attempts to retain attention by mimicking YouTube (and possibly Tubi), combined with how disposable its original content has become, have left the biggest premium streaming platform looking more mortal than ever.

Andrew Sharp argues that after abandoning its Warner Bros. Discovery ambitions, Netflix's shift toward YouTube-style content and increasingly disposable originals have made the once-dominant platform look fragile, amid another stock hit this week.

transcript

Andrew Sharp: I wrote about all of it on Sharp Text this week, where I marvel at how disposable the original content has become and argue that the attempts to retain attention by mimicking YouTube (and possibly Tubi?) have left the biggest premium platform in the world looking more mortal than ever.

Prediction

Reports of OpenAI's new hardware product — an ambient speaker with robotic components — sound like a great first experiment in the hardware category.

Discussing reports of OpenAI's rumored hardware device — an ambient speaker with robotic elements — Andrew Sharp says the concept sounds like a smart first foray into hardware.

transcript

Andrew Sharp: we discussed all these topics, as well the reports of OpenAI's new hardware product — an ambient speaker, with robotic components — and why that idea sounds like a great first experiment in the hardware category.
