We are entering a period where nothing not directly sampled by one's five senses can be trusted. Any electronically recorded evidence can easily be faked and often using off the shelf consumer-grade equipment and software.
The problem (as stated in this article) is that we can't even trust that. Because we only have our memory of what our five senses detect, and these fake videos can alter our memory.
One of the most vivid examples I recall was back in high school, seeing a video that was debunking the myth of "back masking" (having hidden messages when an "evil" metal song was played backwards). They played the same sound clip, with a transcription of the supposed hidden message on the screen, and I could clearly hear that message. Then they played the same clip but with a completely different message on the screen, and I could also distinctly hear that alternate message, in the same sound clip.
Check out the "You Are No So Smart" podcast. The author goes through all of the ways that our brain can be tricked/is tricked in daily life.

For example, in one episode [https://youarenotsosmart.com/2016/10/09/yanss-085-memory-ill...]:
"Julia Shaw’s research demonstrates the fact that there is no reason to believe a memory is more accurate just because it is vivid or detailed. Actually, that’s a potentially dangerous belief.
Shaw used techniques similar to police interrogations, and over the course of three conversations she and her team were able to convince a group of college students that those students had committed a felony crime.
In this episode, you’ll hear her explain how easy it is to implant the kind of false memories that cause people just like you to believe they deserve to go to jail for crimes that never happened and what she suggests police departments should do to avoid such distortions of the truth."
TL/DR: What is reality? How can I even trust my senses?
That podcast is great. Should also be required listening for anyone who does any kind of investment. One reason people keep falling for the same scams over and over is that they think they're too smart to fall for a scam.
