<p>It's possible that Marx was right about that specifically, and that capitalism will destroy itself naturally through sheer technological innovation by automating everything to the point economics becomes irrelevant.<p>I'm deeply suspicious of any socialist or communist who desires to implement a socialist state, however. His prophecy must come true naturally, it cannot be forced via government mandates.<p>Socialists want to get rid of capitalism as the economic model <i>and then</i> transition to post scarcity. I want to keep capitalism until it destroys itself by making everything abundant and automated.<p>There is no need to "seize" anything. We merely need personal manufacturing technology.</p>

<p>I too skip all permissions, but I run the harnesses inside an isolated virtual machine. I took care to firejail Claude Code on my host since day one, and coding my own QEMU VM orchestration solution was among the first things I used it for.<p>Alarm fatigue will quickly destroy any and all "meticulously approve every little command the AI wants to run" workflows. Give it a virtual machine and let it cook. If it blows up the virtual machine while it works, it doesn't matter.</p>

<p>> Were you following any patterns/standards/advice on what you needed to protect against?<p>Just the general knowledge that sharing a kernel with untrusted software is too dangerous, that hardware virtualization is an infinitely smaller attack surface and that <i>the entire industry</i> will be in deep shit if people or AI breaks hypervisors.<p>Initial threat model was supply chain attacks but eventually grew to include AI harnesses as well. Not very worried about them hacking me, more about accident prevention.<p>So that means each VM must be running a completely independent kernel that's fully isolated from the host's file system. They must also have fail closed network filtering built in.<p>> Anything you can point the rest of us to?<p>I have published my virtdev's design document.<p><a href="https://github.com/matheusmoreira/virtdev/blob/master/DESIGN.md" rel="nofollow">https://github.com/matheusmoreira/virtdev/blob/master/DESIGN...</a><p>Yes, it is AI generated.<p>In summary, it's a QEMU VM orchestrator with a base OS image and project specific delta images. VM lifecycle is managed by systemd. System level isolation is already pretty good and it already solves the "AI wiped out my $HOME" problem. I'm currently working on a custom network stack to replace the nftables based firewall.</p>

<p>I did the same thing. It was my first "vibecoded" project. I've been using it every day and it's great. I'm writing a custom Rust network stack for it right now. Gonna replace the current nftables firewall with it.<p>As for Docker Sandboxes, I'll just ask Sol literally right now to see what it does better than my virtdev, and then I'll improve virtdev instead of using Docker.</p>

<p>> the socialists<p>Every socialist wants post scarcity deep down. In fact, it's what Marx promised them since the beginning.<p>Socialism is an ideological and practical dead end. They must be resisted at all costs. It's still an economic model. They won't destroy the economy, they will centralize it in the hands of the state.<p>Don't seize the means of production, <i>distribute them</i>. Give everyone an AI and a replicator.<p>Personal manufacturing capabilities. We must attack things like the very concept of trillion dollar semiconductor fabs. Everybody should be able to make their own things. Just like we can magically conjure up free software on a laptop at home.<p>> neo-luddities<p>Don't know enough about this to write coherently about the subject.<p>> the ones that are for automation are the billionaires<p>Contemptible, but I believe we have better chances of success if we try to collapse capitalism from within.</p>

<p>> does economics support that statement always?<p>Economics itself is the enemy. It is the <i>source</i> of that statement. It's so ubiquitous that we cannot even conceive of a life without it. The friend wanted scarce things, so naturally she wanted everyone in society working to produce those things for her.<p>Economics arise out of <i>scarcity</i>. There is not enough for everyone, therefore we must economize, we must decide who gets the limited amount of goods and resources.<p>We assume everyone should be working because if they aren't they are getting resources without contributing back their own resources, such as their limited time, body and cognition. That's an inherent unfairness, and is the "they're getting a free pass" sentiment that's all too common. I'm working, why aren't they?<p>To fix this, we must somehow achieve the fabled post scarcity society. Automate everything so thoroughly the price of everything becomes literally zero. This destroys the economy. It doesn't matter anymore whether people are working. There is no further need to economize if everything is abundant.<p>"I mean, I’d like to be able to buy more stuff" must still be satisfied, except she doesn't even need to <i>buy</i> it any longer, it just sort of materializes like it grows on trees. That is the dream.<p>Necessary technological upheaval aside, the one major roadblock to achieving the dream is <i>artificial scarcity</i>. We've got corporations conjuring up scarcity <i>where there is none</i>. The internet is the closest to artificial scarcity we've ever been, and it is so subversive it destroys their business models. The entire intellectual property industry must be wiped out if the dream is to be achieved.</p>

<p>I agree with you. I'm also using AI to help me learn electronics so I can finally make some real stuff I can hold in my hands. Lots of hard engineering involved so I'm a lot less confident in my ability to spot the AI's own mistakes.<p>However, saying you can't learn "anything" is just too strong. I'm definitely managing to distill the AI's weights into my own brain.</p>

<p>My account seems to be stuck in some kind of inconsistent state. I opened the Persona verification, closed the tab because I didn't have my documents on me at the time, and then I could never start the Persona verification ever again. Apparently I got rejected without even starting the verification.<p>I ended up sending an email to their data protection officer exercising my LGPD (brazilian GDPR) rights as a data subject. It's my right to know the criteria used, request review and correct any information they have stored about me. Hopefully that'll get them to either clear this inconsistency up or reject me properly from TAC. Plus I get to test if my country's laws have any teeth.</p>

<p>> Until recently, only spies and criminals had to worry this obsessively about their private statements being picked up by electronic equipment.<p>> But soon, the average person might need to deploy surveillance countermeasures.<p>Already there. If you want privacy and anonymity online, you're looking at literal terrorist cell tier tradecraft.
