Ohh, then I'd like these aliens to base their research on my social media accounts. The products would be so fun, and their idea of what's an human so wrong (nope, we are not omnipresent in the religious sense!)
I'm not even speaking about my weird, ultraspecific centers of interest. Location. Despite the fact that the sites are tracking me geographically, algorithms can't make their mind on where I am.
I wonder what aliens would deduct from the fact I'm checking news of Central Canada (that, I do), am interesting in buying real estate in Central Canada (I did not for years), but only buy my furniture in Amman (never been there! Never checked online furniture build there!), and buy makeup from a very specific small mall in Kuwait City (been in that mall, but I don't wear, let alone buy, any makeup). Social media, on the other end, never register the fact that I spend a lot of time in Europe, and mostly post from there. Oh, except when comes the time to tell me that the fair is in town in Lubeck. Where I've not been since at least 10 years.
The ineptitude of algorithms is not only a bit reassuring (not for long, I know), it would also make a unskilled marketing agency do amusing mistakes.
