Here is a well-written summary of why it is important to keep things about you hidden to other entities.

No, you have something to hide

I’m sure these implants will give much needed ease to patients who suffer frem tremors like parkinson and other neurological diseases. But the things I’m mostly concerned about are:

• Will health insurance pay for the implant in a one-time-payment? Will it be a subscription model? What happens when you can’t pay your subscription? Will it be shut off?
• Will the implant be operated through firmware (like a pacemaker) or software, which reqires frequent updates? If so, will there be - like computer software - “new features” implemented (“With version 2.0 you will be able to share your Neuralink experience with other Neuralink users. Your data may not be leaked, pinky promise.”
• What if a certain mentally unstable CEO throws a tantrum that will affect the performance of the Neuralink implant negatively? Will there be any legal protection from such thing?

The simple fix really gave me a sense of joy and satisfaction. It feels great to extend the use of something that I already have rather than need to consume more.

Also sometimes it feels like cheating the system. A new purchase will be postponed.

Back when I had a printer I have bought ink refill kits off of ebay and refilled the empty ink cardridge with a syringe. It worked well and I could extend the lifespan up to three time for each cartridge. After the third refill cycle I had to buy new cardridges. Meanwhile the manufacturer re-designed the label and switched the colors on that label - imagine it like this: when looking from above the compartment of the cartridge, the colors were: cyan - yellow - magenta. After the re-design of the label the colors were: cyan - magenta - yellow, indicating that the locations of said colors were different. When refilling with a syringe it happened that now the wrong ink was applied (magenta got mixed with yellow and vice versa), rendering the cartridge unusable. I was forced to buy the expensive original ink. Anyway, the printer later became unrepairable when a tiny piece of plastic broke inside the printer because I was moving it into a different place. I don’t own a printer anymore.

Another time I replaced the battery of my 2010 macbook pro, along with a RAM upgrade an a cleaning of the fans. I used the tutorial on ifixedit. I also bought their tool set - which I can strongly recommend when working with delicate hardware.

And then there was this super cheap bluetooth mouse which came without a power switch. As long the two batteries were inserted, it was ON! I managed to place an old switch from an old computer tower case at the underside of the mouse so the mouse could be shut off without losing battery charge. I still have that mouse as an emergency backup. Given its price the left click switch has been worn off after just one year of usage - it somtimes double-clicks.

Repairing things can be good for the budget and also good for the enviroment - but it makes you a bad customer ;-)
