<p>To anyone upgrading their daily driver Mac this year, are you considering going to a Max + high memory config? eg. with the hope (now or in near future) of being able to do usefully run agents/LLMs locally on your main machine?<p>Or is the few extra thousand dollars difference between a base and max-spec MBP still just better spent on literally any other practical option (like different harware, remote hardware, cloud AI subscriptions or credits). Or wait to see if there will be an M5 Studio or what inferencing performance next year's M6 may bring?<p>I am tempted, but even with some new models getting skinnier and more efficient, I am not sure moore's law and the M5 generation is quite there yet to be worth the trouble?<p>What call's are ya'll making and why?</p>

<p>For anyone actually using OpenClaw or related claw/agentic frameworks, how are you solving for your agents, plugin installers etc, self editing and corrupting your settings.json configs?<p>Problems I'm seeing:
- spending 80% of time troubleshooting the agent framework, vs doing constructive projects
- agents writing without reading first
- concurrency issues, agents reading from stale memory
- agents not consistently backing up before chantes
- no built-in safety controls for rolling back to last good config
- intallers or plugins stomping all over the file
- schema constantly changing and agents not checking docs and then hallucinating syntax
- basic problems with json (no comments, no types, very fragile to syntax errors)
- even small errors will block gateway from restarting and block the agents from being able to run to autonomously troubleshoot or fix their own mistakes.
- openclaw doctor seems to cause as many problems as it fixes<p>I find myself setting up a lot of scripts, scaffolding, and external AI tools, just to babysit an agentic framework. Which sort of defeats the purpose of using a "ready-made" framework in the first place? Or is there an easier way?</p>

<p>Closest thing to a usecase I can think of are all military in nature. There's an argument that AI in space only begins to make any sense if the data source you are processing is also originating in space, and you need (for reasons) to run models on it in space before downlinking the results.<p>Maybe there's a very latency sensitive need to send realtime targeting information to a tomahawk missile in flight? But it's also too bandwidth, compute or cost intensive to send a firehose of raw spy-satellite data to a disposable one-way attack munition?<p>The data centers in space are actually for the spy satellites to use. That's all I got for practical applications.</p>

<p>It's not just chat. Remember image and video generation are on the table. There are already a huge category of adult video 'games' of this nature. I think they use combos of pre-rendered and dynamic content. But really not hard to imagine a near future that interactive and completely personalized AI porn in full 4kHDR or VR is constantly and near-instantly available. I have no idea the broader social implications of all that, but the tech itself feels inevitable and nearly here.</p>

<p>Either M5 Pro chips are finally here... or March is just the next time Apple can source any DRAM or SSD chips for the existing line!<p>In all seriousness, I am quite concerned for what the base model and upgrade pricing is going to be for the full M5 line, given the recent AI-driven DRAM supply apocalypse.</p>

<p>Ships of that era and leader had castles on both ends fore and aft. It's just the forward one than retained in usage as a sailing term, even after foredecks no longer looked like castles. The aft castle became a quarterdeck, a poop deck, a cockpit or a bridge etc.<p>Meanwhile, a built-up and elevated stern 'castle' is advantageous place to put the steering and command position, close to the rudder and with visibility of the whole ship, it's rig,  plus where the ship is going. While maximizing mid-ship area for cargo. If you have to pick one end or the other, stern is the more comfortable end of the ship being most sheltered from wave action and weather. Being elevated and fortified also helps as a fighting/defensive position, but that is less important for modern cargo ships. 'Anticipation' isn't quite the right word as shipbuilders have always worked within the same basic design considerations and trade-offs, as the sea itself continues to enforce the same fundamental constraints.</p>

<p>[this is a reply to fourseventy]
Looking up the violent crime rates by migrants in places like MN, it's effectively zero. As a rule, migrants and immigrants don't commit crimes at anything close to the rate of native US citizens.<p>Meanwhile in Minneapolis, the overwhelming majority of violent crimes (including aggravated assaults, theft, murders and sexual assaults) are being committed by ICE agents.</p>

<p>So Zen 6/7 will have a core design and a CCD design. But like past gens, these will be packaged into different products with different sockets and packages (everything from monolithic APUs to sprawling multi-chiplet Server cpus).<p>So to say that Zen 6/7 supports AM5 on desktop, doesn't necessarily exclude that Zen 6/7 product family in general doesn't support other new/interesting sockets on desktop (or mobile) also. Maybe products for AM6 and AM5 from the same zen family.<p>Medusa Halo and the Zen7 based 'Grimlock Halo' version might be the interesting ones to watch (if you like efficient Apple-stlyle big APUs with all the memory bandwidth)</p>

<p>Undoubtedly each new model from OpenAi has numerous training and orchestration improvements etc.<p>But how much of each product they release also just a factor of how much they are willing to spend on inference per query in order to stay competitive?<p>I always wonder how much is technical change vs turning a knob up and down on hardware and power consumption.<p>GTP5.0 for example seemed like a lot of changes more for OpenAI's internal benefit (terser responses, dynamic 'auto' mode to scale down thinking when not required etc.)<p>Wondering if GPT5.2 is also case of them in 'code red mode' just turning what they already have up to 11 as a fastest way to respond to fiercer competion.</p>

<p>Either way, you are right to point out that it important to only a try a pattern like this if your clients are highly trusted (or/and have additional compensating controls against DDOS threats). It would be beneficial if the OP made more explicit what their client/server relationships and also flagged the risk you mentioned for general audiences not to go implementing such a solution in the wrong places.</p>

<p>Thanks for calling this out. Here is a better comparison. Before Google was founded, the market for online search advertising was negligible. But the global market for all advertising media spend was on the order of 400B (NYT 1998). Today, Google's advertising revenue is around 260B / year or about 60% of the <i>entire</i> global advertising spend circa 1998.<p>If you think of openAI like a new google, as in a new category-defining primary channel for consumers to search and discover products. Well, 2% does seem pretty low.</p>

<p>What you are describing has been proposed before, for example within context of projects like Breakthrough Starshot. In that the case the idea is to launch thousands of probes, each weighing only a few grams or less, and accelerating them to an appreciable fraction of the speed of light using solar sails and (powerful) earth-based lasers. The probes could reach alpha centauri within 20-30 years. There seems to be some debate though about whether cross-links between probes to enable relaying signals is ever practical from a power and mass perspective vs a single very large receiver on earth.</p>

<p>It seems like strixhalo is a pipe-cleaner part of sorts and the real deal may have to be Medusa Halo. That one could be a monster. The bad news is that it sounds like it's a long way off (2027 sometime) so who knows what Apple M5 or M6 Max could look like by then for competition.</p>

<p>America is trapped in a cycle where political parties have discovered that fear and anger drives voters whereas contentment with status quo does not motivate turnout. This leads to a scenario where parties will actively sabotage the resolution of painpoint issues such as immigration, healthcare, gun control etc. so long as it continues to create anger and fear that they can successfully blame on the other party. This behavior extends to voting against their own proposed policies in the interest of seizing/maintaining power over problem solving. And now deliberately creating crises (both real and fictional ones) has become the game-theory dominant strategy in American politics.</p>
