A new way to plug a human brain into a computer: Via veins
https://arstechnica.com/science/2020/10/a-new-way-to-plug-a-human-brain-into-a-computer-via-veins/

.......... a team of scientists and engineers showed results from a promising new approach. It involves mounting electrodes on an expandable, springy tube called a stent and threading it through a blood vessel that leads to the brain.

“It’s fully implantable. Patients go home in a couple of days. And it’s plug-and-play.”


It took training once the subjects got home. The electrode-studded stent could pick up signals from the brain, but machine-learning algorithms have to figure out what those signals—imperfect reflections of a mind at work even under ideal conditions—actually represent. But after a few weeks of work, both patients could use an eye tracker to move a cursor and then click with a thought, using the implant. It doesn’t sound like much, but that was enough for both of them to send text messages, shop online, and otherwise perform activities of digital daily life.
I suspect the Department of Defense is quite interested.

The issue is morality and ethics.

The first human to fabricate a spear probably thought it a good idea for hunting his food.
And then another human realized it could make a decent weapon, so he made it smaller, lighter and devised a means to propel it, a bow.
And it became a weapon useful for aggression against numerous humans.
But the arrow and spear were necessary for survival----> food gathering.

Man wanted to harness the energy of the atom. And humanity wound up with and used atomic bombs. A weapon capable of being used against large masses of humans and was used.
While energy generation by fission is radioactively dirty, the quest to generate electricity cleanly by fusion continues.
In a high tech society, large amounts of energy are necessary for survival.

Technology is easily perverted from it's first intended usage.

Possibilities with this tech, also.
On the plus side, advances in medicine.

It's why we now have laws concerning specific usage of certain technologies.

I'd be more worried about the political activist or the military using it than a doctor.
But even with a doctor/scientist, the safety factor is and always will be the accepted morality and ethics of the issue at hand. Defining how the technology is to be used.
