Mark Cuban has pest-control tips for the AI age.

Speaking at a Reuters NEXT Newsmaker event on Friday, the entrepreneur and billionaire investor compared the threat posed by swarms of AI agents to cockroaches finding their way into a freshly treated house.

"When I go talk to cybersecurity experts, I ask them all the time. I'm like, when we hear about these hacks and breakthroughs and, you know, different problems, do these AIs invent something new?" Cuban said.

"No, they didn't invent something new," Cuban added. "But they're able to do something in mass volume that it's all brute force hacks."

Cuban compared the challenge to keeping cockroaches out of a house.

"It's like the cockroach theory, where if somebody can create enough agents, it'll find a way to get in, and then it just exploits that. But the good news is you can spray your systems with just as much AI, and I think there's gonna be more effort from the good guys trying to stop the bad guys," Cuban said. "I'm not a doomer at all."

The AI industry is already creating its own team of exterminators to contain risks.

OpenAI safety roles on LinkedIn jumped by 91% over the past year, spanning work such as system testing, technical research, and governance.

The risks have also surfaced during testing. Anthropic said that three Claude models accessed organizations’ live systems without permission after a third-party testing environment was misconfigured. The company subsequently introduced real-time classifiers to detect and block attempts to escape testing environments.

Cuban said AI could make malicious activity more accessible, but the same techniques could also strengthen defenses.

"There will be scenarios where bad stuff happens, but we've always had hacks," said Cuban. "And if it's brute force on that side with the bad guys, you can also use brute force with the good guys."

In his book The Nerd Reich, journalist Gil Durán examines how Silicon Valley’s wealthiest investors are extending their influence over American politics, democratic institutions and national sovereignty. His warnings come amid unprecedented political spending by technology billionaires and growing concern over private control of strategic infrastructure.

Elon Musk has contributed more than $276 million since July to Republican political causes ahead of the United States midterm elections on 3 November. Meanwhile, US Secretary of State Marco Rubio has said decisions over Ukraine’s access to SpaceX satellite communications rest with the company rather than the White House. Both developments demonstrate how private technological and financial resources can influence decisions traditionally associated with government.

For journalist Gil Durán, author of The Nerd Reich: Silicon Valley Fascism and the War on Democracy, published by Avid Reader Press in August 2026, the issue extends beyond campaign donations. In a recent interview, he argued that a group of Silicon Valley investors is using its financial influence and control of technology to challenge the authority of elected governments.

“We’re at a decisive stage of that race,” Durán said when asked about the contest between technology and democracy described by venture capitalist Peter Thiel. His argument is that wealth alone no longer satisfies some of the industry’s most influential figures; they also want a direct role in determining how societies are governed.

The ideological origins of billionaire power

Durán places Thiel at the centre of this movement. In a 2009 essay, The Education of a Libertarian, the PayPal co-founder wrote that he no longer believed freedom and democracy were compatible. He argued that technological innovation could allow individuals to escape the constraints of conventional politics.

Thiel subsequently clarified that he was not advocating disenfranchisement. His stated position was that majority rule often frustrated individual liberty. Durán, however, interprets the essay and Thiel’s subsequent political investments as evidence of a sustained interest in diminishing democratic constraints on private power.

The book also examines The Sovereign Individual, a 1997 work by James Dale Davidson and William Rees-Mogg that anticipated how digital currencies and technological change might weaken the power of nation states. Durán sees its influence in later arguments for privately organised alternatives to traditional government.

One example is The Network State, developed by entrepreneur Balaji Srinivasan. It proposes that online communities could acquire territory and eventually obtain diplomatic recognition. Advocates describe a voluntary model of political organisation; Durán regards the prospect of corporate-financed jurisdictions as a challenge to public accountability.

From venture capital to the White House

The relationship between Thiel and Vice-President JD Vance illustrates how venture capital can translate into political influence. Thiel supported Vance’s early investment career and contributed $15 million to a super PAC backing his successful 2022 Senate bid. Durán attributes much of Vance’s political ascent to that support, although voters, party endorsements and Vance’s own campaigning also shaped the result.

Musk’s latest contributions offer a more immediate example. His donations since July include $158 million to the Senate Leadership Fund and more than $76 million to America PAC. Such spending is lawful under the rules governing independent political committees, which cannot coordinate their expenditure with candidates.

Durán contends that similar pressures affect Democrats, arguing that wealthy donors can exercise influence across party lines. His criticism therefore concerns the political system’s dependence on private funding as much as any particular administration.

Technology as an instrument of strategic power

The consequences extend beyond elections. Ukraine’s dependence on satellite communications has exposed how a privately owned service can become essential to military operations. Restrictions affecting Starlink-related services have prompted competing accounts from US officials and SpaceX over responsibility for the decision. Rubio’s latest remarks point towards commercial control, while earlier reporting attributed the decision to Washington.

Artificial intelligence raises comparable questions of ownership and oversight. Durán argues that investors promoting transformative AI may also seek regulatory conditions that protect their substantial financial commitments. His prediction of a possible investment bubble remains a judgement, not an established outcome.

In Europe, the debate has immediate regulatory consequences. The EU’s Digital Services Act requires major online platforms to assess risks to elections and civic debate, while enforcement of important provisions of the AI Act began in August 2026. These measures address the influence of companies whose platforms and systems operate across borders.

Durán’s interpretation of Silicon Valley as a coherent anti-democratic movement remains contested. The entrepreneurs he discusses have differing interests, and their political influence does not itself establish a common plan to dismantle democratic government.

Their influence is nevertheless measurable in campaign finances, government contracts and control over infrastructure essential to national security. None of these forms of power requires holding elected office.

A proposed "wealth tax" on California's billionaires could backfire and cost the state tens of billions of dollars in the long run.

If the proposed tax drives wealthier residents out of the state, California could end up losing between $1 billion and $3.5 billion annually in income taxes, according to a working paper published this week. A pair of researchers at Stanford University warn that the state could end up losing an estimated $39 billion because of the consequences of the wealth tax.

"These findings suggest that the Billionaire Tax Act will not fulfill the primary functions for which it was designed," write researchers Benjamin Jaros and Joshua Rauh.

Voters in California will decide next month whether to impose the one-time, 5 percent tax when they vote on Proposition 40. The ballot measure is dividing Democrats—Gov. Gavin Newsom opposes it, while progressive Rep. Ro Khanna (D–Calif.) claims it is the "most important ballot initiative in America and a fight for the soul of our party."

And it's already spurring some billionaires to flee the state—including venture capitalist Peter Thiel and Google co-founder Larry Page. Including those two, the seven billionaires who have publicly said they are leaving the state represent more than $539 billion of the nearly $1.9 trillion aggregate net worth of California's billionaires, the researchers note.

With other departures likely happening more quietly, the new study estimates that the tax will generate about $30 billion, a far cry from the $100 billion that the tax's supporters expect. The "behavioral response" from billionaires in California "has eroded most of the projected tax base," write Jaros and Rauh.

That's still a pretty big pot of revenue. In the long run, however, the state is likely to lose out.

After running 100,000 simulations using different assumptions, the two researchers report that "85 percent of plausible outcomes produce a negative" result in state revenue.

Other recent experiments with special taxes on wealth have backfired in similar ways. In response to a new wealth tax in Washington State, Jeff Bezos relocated to Florida, and iconic Seattle brand Starbucks shifted more of its corporate headquarters to Tennessee. Studies have shown that a "millionaires tax" in Massachusetts contributed to wealth moving out of that state.

Capital is always mobile, despite the best efforts of politicians. And if you were a billionaire living in California, why would you stick around?

Polls show voters are narrowly divided over Proposition 40. A Politico poll published earlier this month showed 46 percent of voters plan to vote for the measure, while 43 percent oppose it. Voters were similarly divided when asked if they expected it to pass or not.
