207 predictions · 379 assertions · 186 opinions · 276 insights · 60 disclosures · 11 what ifs · every statement was checked. The predictions and assertions are the 586 claims: statements the public record can support or contradict. 234 are resolved, 18 are not yet assessed, and 334 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.
The record, in short
What the tape says about how Marc argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.
Their most notable supported claim
Their most notable contradicted claim
Expressed certainty vs assessment result
weighted support: a fully supported claim counts one, a partly supported claim counts half. Each filled bar is clickable and opens exactly those claims; "none yet" means nothing said at that certainty level has resolved yet

How they sound: speaking style how? →
324 words/min while actually speaking · 30.7 um and uh per 1k words · 39.2 false starts per 1k · 26.8% of pauses land inside a clause
Um and uh per 1,000 words, year by year. Hover a point for the year's tape.
Measured by listening to the audio itself: 607,998 words across 77 episodes of raw-level tape, transcribed verbatim with every um and uh kept, each one attributed only where the alignment onto our timed stream is unambiguous. These are measurements of speaking style. We do not rank them: across this corpus, fluency and argument quality are nearly uncorrelated (ρ≈0.2), and smooth talking does not signal clear thinking.

Andreessen: Proposed AI compute limits will entrench monopolies and destroy startups

Andreessen: Defense prime contractors function primarily as political lobbying operations

Andreessen: Unrealized gains tax threshold will drop to hit startup workers
“Inevitably this, the threshold is going to walk down and it's going to end. You just tell what's going to happen. It's going to go to 50 and then 20 and then five million and then one million. It's going to walk all the way down and it's going to hit, number o…”
Andreessen unilaterally created the HTML image tag as a fait accompli
“We weren't making progress on it, and then I just did a, because I controlled, you know, I controlled Mosaic at that point, so I just did a fait accompli, and I just declared it, and I created the image tag.”
Andreessen: AI incumbent lobbyists exist today because the internet was open
“Again, ironically, and some, and to your point, ironically, some of the companies that are lobbying hardest for regulatory capture and cartel, you know, kind of government cartel status for AI are companies that exist today because the internet was open.”
Andreessen opposes locking down AI models, cheering on open jailbreaks

Andreessen: California high-speed rail spent $10B with zero ground broken
“The California high-speed rail project. Which is now ten billion, it's over ten billion in spend with zero ground broken.”
Andreessen: Media narratives about tech jump directly from useless to evil
“And then basically within like five years, it was like Facebook is like the living demon incarnate on earth and destroying everything. Right? It went from like useless to evil in one step. Right? You know, the headline never gets never just like, oh, this is k…”
Andreessen: Generative AI prompts will render manual pixel editing obsolete
“Because you'll live in this new world, and in the new world, you'll just tell the machine what you want for a photo, for an image, and it'll generate you as many options as you want, and it's generating you something that's better than you would have been able…”
Andreessen: U.S. manual manufacturing jobs will never return without technology leaps

Andreessen: Software startup costs will rise due to the Jevons Paradox
“And so the paradox here would be, yes, the cost of developing any given piece of software falls, but the re, the reaction to that is a massive surge of demand for software capabilities. And so the result of that actually is, although it even, it looks like sta…”
Andreessen: Proprietary corporate data is not a defensible AI moat
“And so your proprietary data as, you know, company X will be a little bit useful on the margin, but it's not actually going to move the needle. And it's not really going to be a barrier to entry in most cases.”
Andreessen: Automating management may be easier than automating frontline workers
“Maybe it's actually easier to automate the manager job than it is the worker job.”
Andreessen: Ubiquitous video conferencing renders traditional immigration law less relevant
“With sort of sufficiently advanced, ubiquitous video conferencing all of a sudden immigration law becomes less relevant, right? Because like if, you know, it's perfectly legal to stream bits across the border even if it's not possible for people to move across…”
Andreessen: FDIC blocked private equity and bank bids to buy SVB
“There were both there were other big banks that wanted to buy SVB, and there were private equity firms that wanted to buy SVB, and basically do a private sector bailout requiring no, no taxpayer involvement, and the FDIC actually blocked those also.”
Andreessen: Centralized authorities will lose all public respect within ten years

Andreessen: Remote work productivity loss is a fake problem
“My view is that's actually a fake problem. That, that, that the real problem was they weren't working hard to begin with. And they were goofing off 20 hours a week in the office already. And so yeah, they're goofing off at home, but they were goofing off in th…”
Andreessen: Generative AI will easily replace white-collar email jobs within five years
“As the generative AI revolution hits white-collar work, you know, over the next five years, like, I suspect, I'll put it this way, a reason for bullishness on AI in the workplace is I suspect it may be easier than it looks to replace a lot of white-collar work…”
Andreessen: Big tech HR drives political and social agenda
“At a lot of companies, including a lot of big tech companies, it's HR has a charter to basically drive political and social change and enforce that change. Very broadly inside the organization, right?”
Andreessen: Bashing China and Big Tech are Washington's only unifying issues
“Look, if there's a unifying issue, there's basically two unifying issues in Washington. One is they don't like China and the other is they don't like big tech. And so, you know, this is a winnable war. Like, this is a winnable war on behalf of startups and ope…”
Andreessen: Anthropic is aggressively lobbying for regulatory capture in D.C.
“Anthropic is very much in the group of kind of big tech, you know, kind of new incumbent big tech, you know, lobbying very aggressively for regulation and regulatory capture. In D.C., and so I think it's sort of an open question whether Amazon is going to pick…”
Andreessen: All harmful AI uses are already illegal under existing laws
“As far as I can tell, every single use of AI to do something bad is already illegal under current laws and regulations.”
Andreessen: Post-hoc detection of AI-generated content will not work

“Like, us as a firm, like, technically, I'm really the CEO, but, like, Mark is more the brand, I would say, in terms of he just does way more media than I do. And that works, but it works because it's Andreessen Horowitz, and nobody knows the fucking difference…”
a16z built partner brands so founders wouldn't only demand Marc Andreessen

Horowitz: Delayed browser creation would have enabled proprietary network monopolies

Horowitz: Public Attacks Bother a16z Staff More Than Founders
