RAW vs JPG

"When I was Young", I learned Z80 assembler over a weekend. The next weekend, I disassembled the multiply and divide routines in the Microsoft FORTRAN-80 compiler for CP/m. Rewrote them, mine took half the time to run.

Yeah, you can do that when Marketing is not involved in the project. LOL CP/M? Really??
 
An interesting (well, to me) thought.

I am sufficiently concerned about my images that I take JPEGs uncompressed.

Am I doing something right here? Or something wrong?

And will AI come to my rescue to sort everything out?

Badly expressed thoughts aside, my greatest concern with AI has to do with the social (societal?) aspects of it. The loss of jobs it will cause, notably in human-staffed call centers as are nowadays used by so many businesses, when AI comes into general use, as we seem to be headed towards at lightning speed.

As inefficient as they can be and usually are, call centers create work for humans. To move forth to another simplistic idea, while business owners salivate at the thought of the money they will save by letting computers do their customer service, the cost to us generally will be in the loss of revenue caused by unemployment. And the loss of business to business. A vicious circle here, but a potentially dangerous one.

Am I thinking this out right, or on a wrong track? Or have I just taken this thread off-topic again? The latter two are somethings I'm used to...
 
I don't think there is any such thing as an uncompressed JPEG. They are all compressed to some degree.

I share your concerns about AI. Look at what retailers have done with self checkout at grocery stores and big box stores. Loss of jobs for cashiers, terrible experience for customers, and all of the retailers are doing it so customers have no choice. But the corporations increase their bottom lines, so screw the customers and especially the employees. AI will be this but several orders of magnitude greater.
 
AI is the worst thing that is happening to humanity.

We are creating our own death.

The more I think of it, the more I am starting to agree with the underground notion that ancient egypt were so evolved and disappeared. We will disappear too, that’s for sure. Thanks to robots and AI… will be be able to sustain humanity for another 1000 years with all this bullshit coming our way? No. Stretch this to 1000
Years and there it is: wars, the extinction of our cultures and major breakdown, and the birth of new simple people with a simple economy: gold, exchanges…

All in all, the circle going round.
 
I use raw on my 2:3 cameras. I have always used RAW. However, I wanted to use 1:1 on my Fuji GFX and started using jpegs on that camera. Honestly, I was still able to edit the jpegs so much that I have relaxed about it. I can use both and be perfectly fine.

To shoot RAW 1:1 on the GFX you have to enable RAW + JPG and when you import into Lightroom it recognizes the 1:1 crop in the RAW file
 
I always shoot RAW + JPG when I have the option. And I always shoot the largest JPG fir possible when offered the option.

OK, AI. When cars came in buggy whip fabricators were replaced by mechanics. When Gutenberg came along scribes were replaced by pressmen. When computers came along a whole new field of computer attendants appeared, i.e., programmers,architects, analysts and so on.. AI has been around in simpler forms for years now. An example is "point and shoot" and there are others. It is now more sophisticated. It runs on electricity. If it is a bad dog, unplug it.

Think about whether you could even manage your affairs these days, let alone in the future, with your computer unplugged. I don't have a smart phone, and find that I am constantly encountering major inconveniences because of that, despite the fact that I'm retired and live as simply and quietly as possible. When the rest of the world heartily embraces a technology (even one that operates under-the-radar against their best interests), it becomes almost impossible not to succumb.

My man, it’s never you who will unplug it. They will plug, or unplug.

Planes without pilots, shared cars without drivers. No more dollars, only digits, no more real currency backed my credit but only credit… we won’t be able to unplug nothing.
I’m way off topic…

That is true: there is "Lossless Compressed JPEG" just as there is Lossless Compressed DNG and other vendor-specific Raw formats.
Lossless JPEG uses Discrete Cosine Transform and stores all of the frequency information. Compression using Huffman Code typically gets 2:1 to 3:1 compression.

When I accepted a new position at my work in 1982 I was asked to give my word I'd stay for two years. The job was developing data acquisition and image processing algorithms for digital IR sensors. I told them unless someone offers me a job programming a HAL-9000 I would stay. My first computer was a $8M parallel pipeline vector Supercomputer. Most advanced instruction set of any computer I've used, collapse a 3-deep loop processing three-dimensional arrays into a single Assembly language instruction. Makes the instruction set of modern computers look boring. We had an AI shop back then too- in 1980. Told them the same thing I told my Nephew working AI now- AI vs NS, AI does not stand a chance. Natural Stupidity wins every time.
