Personally, I'm very skeptical of what the article claims. UK Mainstream media seems to derive pleasure from misleading the general public with sensationalist headlines - like claiming that scientists 'know' how to 'upload knowledge to your brain'. There is no convincing evidence to support what the headline claims. Cranial stimulation methods ( https://en.wikipedia.org/wiki/Transcranial_magnetic_stimulation ) do have a noticeable affect on human beings, but in very limited and specific ways. This isn't the same as being able to directly 'upload' things into brains to alter conscious experiences.
The whole concept of 'uploading' information to a human brain hinges on the shaky foundations of materialist philosophy. Despite what some neuroscientists claim, they still haven't been able to overcome the 'hard problem of consciousness': https://en.wikipedia.org/wiki/Hard_problem_of_consciousness
Although I don't agree with what the article claims, I believe that all freedom loving individuals should do everything possible to challenge the trans-humanist agenda, especially government funded projects to manipulate 'brains' with a view to making it easier to control human behaviour.
It is worth pointing out that a number of manipulative 'brain-washing' programs do exist, and if successful they will surely be used against in harmful ways. So even though I think materialist philosophy is flawed, we still need to be careful. DAARPA and the BRAIN Initiative are a good example of the types of projects in development: https://en.wikipedia.org/wiki/BRAIN_Initiative
I also suspect that state-funded brain manipulation projects aren't advancing quite as smoothly as some people claim, which is probably why the elites are trying to make humans more dependent on centralized technologies and dumb-phones, and encouraging us to be behave more 'machine' like (no one 'falls in love' anymore because even dating is done algorithimically). So, the more we behave like robots, and the more we delegate our mental faculties to algorithms and automated machine-based processes, the easier we are to control through good old fashioned Edward Bernay's style propaganda.
I'll end this post by sharing something that challenges the premises of scientism, trans-humanism and materialist philosophy. Bernardo Kastrup gave a very good talk at the 2015 Alzheimer symposium.I think you'll find it interesting:
