For the best?
Have you been watching any news for literally the past 5+ years? Our governments have thousands of computer science experts and have likely spent trillions of dollars over the last ten years and they can't even keep from getting hacked and having their own secure systems from being compromised. The same goes for many of the worlds top tech companies who also have plenty of resources to keep their products and systems secure. They can't be entrusted to maintain 100% security nor can they be trusted to not be actively exploiting security.
And you think it's smart to interface your brain with a chip? No thank you. You couldn't give me all the money and freedom in the world to take that risk. When a tech company has a 20 year provable track record of 100% secure systems, then I might consider tech implants. I ain't holdin my breath though.
You are right. This author of the post sees the benefits and ignores the risks. However there is a strong possibility that brain implants ( and other implants ) will be used voluntarily and will eventually be something you are "forced" to use because otherwise you will be at severe economic and social disadvantage.
Excellent post!
I don't think systems will ever be 100% secure!
