Hmm, Brain Interface Technology Is a lot older then you guys think. The first time Brain wave was detected was in 1875, " Two Full years Before The Light Bulb was invented btw" by Hans berger,
Ever Wonder About Your Brain Waves? Since that time, Technology has progressed a great deal, understanding of the Brain and it's various functions have been Recorded since 1925 But this Didn't become widespread until the 1950s
when EGG use became widespread for brainwave detection. Since this time we have learned to Manipulate machines using our minds while connected to them, By simply assigning functions to different emotional states which agitate the five different brain wave states humans produce,

Of course, Our technology and understanding of the Mind have come a great distance since the 1950's We are now building machines that can actually record the brain waves and to some small degree interpret them I present a Machine that can record your dreams and playback videos.
Skip to 4:30 to see the machine in action.
This Video is old, It's from 2014, Imagine how far it's advanced since then.
The Ultimate idea here is, As Technology and Understanding of how our brains function progress, So does what technology allows progress.
Not only are we already at a stage that if someone with enough power and wealth wanted to, But They could also know all your most private thoughts, Simply by scanning your brain waves and allowing a computer time to render this information into a form of media we can use in a computer.
Mind uploading, Is all the rage atm, The idea here is, They record your brainwaves for a period of time, All five states, And they create an image file or, "ROM" This rom is an approximation of all brain activity you possess in that period of time, And Truthfully, The more technology progresses, The Minds/Roms will be one day emulated in machines, While You yourself will still experience the bitter pangs of death, Some fantastic replication of your mind can "exist" onward.
I leave you with this article on whole brain emulation.

The Deal is, Are Aliens Real? Well Yeah. But I think people Vastly underestimate us, humans. The first lightbulb was created in 1879. And look where we are now?
Was It aliens? Maybe. But, You know, Us humans have a pretty good progressive track record of amazing achievement as well.
