      So you're saying toss the baby out with the bathwater? @txab posted article was her take on how AI can be used to manipulate pricing as it already does and has been rebuked by the judiciasry in housing. How AI can be and is used to maximize refinery or even Amazon operations all of which are true but because she is who she is; that makes what she says about what is true, false? Is that something akin to Pre-justice aka prejudice?    Look, I'm first in line to approach all information with caution just because we live in a world where people like to lie about someone or something with such a straight face and in such volume that it makes digging to the truth wearisome. Meaning I understand the skepticisms but if I were to toss out everything a person is for a view they hold then my pool of people to draw wisdom from would be non-existent and I'd be forced to reinvent the wheel daily. Not practical.    "Be innocent as a dove but as cautious as a serpent."    Test each word. Every good lie is part truth or no one would believe it. Find the truth in it and reject what isn't.    On this one, AI is being used to do what has been done by hand for hundreds of years already but at such speed, the point of a computer, that it is more easily monetized. This one wasn't that hard a lift.    I wrote a few formulas in a Lotus 123 program decades ago, a series of linked Macros actually, that allowed a daily inventory to be turned into a running P&L and production plan. Something that took three departments a week to assemble now took the time it takes to input the 'daily changes' in inventory. Later that was ungraded to the more powerful Excel program an and integrated with bar code scanning, inventory to supply was done once per shift. It had a huge impact on production scheduling, Seamless interruption flexibility, inventory error reduction, raw materials cost effective utilization and scrap reduction. Huge improvement in the bottom line. I spent months on that and AI could have done it in minutes. So yes, it not only can be used, they would be foolish to not try. The legality, ethics and morality are not the domain of AI. Humans need to keep a reign on it.

      How to Tune 6L80 Silverado transmission

      By ballencd · Posted

      New to this forum.  Also looking to tune a 6L80 and trying to work out all the issues in my transmission swap.  I have a 6.2 diesel (1983) and have removed the TH-400 and about to put in a 6L80 with a TCM-2600 interface and don't have a clue what I doing after that.  Did you (Leatherneck/RAV3) get your slip resolved? I too hate to spend that kind of money on a tuner that hopefully I will not need too many times although from what steelerdude15 added about the HP Tuner being great for diagnostics would be a plus.  I am also from WNC but below you in Columbus.  Any helo would be greatly appreciated.

      It's like saying Bill O'Reilly is "just" a journalist.         Lauren Fix, widely known as "The Car Coach," is a prominent automotive journalist, television personality, and self-identified conservative. She is a frequent contributor to right-leaning networks and platforms, offering commentary that intersects the automotive industry, consumer economics, and conservative political perspectives. [1, 2, 3] Media and Commentary Network Contributions: Fix serves as the National Automotive Correspondent for Newsmax and is a frequent guest on Fox News and Fox Business. Video Platforms: She has contributed to PragerU, where she has hosted videos critiquing government mandates on vehicles. [1, 2, 3] Core Positions Anti-EV Mandates & Fuel Policies: Fix regularly critiques government subsidies and mandates for electric vehicles (EVs), framing them as impractical and burdensome to the average consumer. She advocates for consumer choice and supports traditional internal combustion engine vehicles. [1, 2, 3] Economic Analysis: Her commentary often emphasizes the impacts of fuel prices, inflation, and federal regulations on drivers. [1, 2, 3] Political Alignment: On her public channels, she actively supports deregulation, "drill baby drill" energy policies, and the removal of government restrictions on auto sales and manufacturing. [1, 2] For analysis from Lauren Fix on how consumer automotive choices can align with political leanings:
