Bots are programs created by humans to automate repetitive tasks in the Internet. In the widest sense, the emergence of bots is a manifestation of the process of worldwide automatization that we currently experience in our modern times.
My conjecture is: Automated programs behave not the same as real human beings.
Before we can classify behavioral data as either bot-like or human, we have to record and collect it.
Each of the above events is assigned a timestamp obtained with performance.now().
The above process yields a time series of behavioral interaction data such as for example:

Humans behave like a chaotic systems.
Humans move their mouse, keyboard, touch screen and scrolling wheel in an organic fashion. Bots still have a hard time to mimic mouse movements and touchscreen taps like real humans.
A simple process to distinguish bots from real humans based on behavioral data could look like the following:
That is way easier said than done. However, there are some companies such as biocatch and perimeterx that are already using this approach since years.
But what exactly makes mouse or touch event interaction in a browser human? What are features that are extremely hard to emulate mechanically? Some rough ideas (replace mouse with touch events in case of mobile devices):
The established method to distinguish humans from bots is the good old captcha. However, we are approaching an age where captchas can be solved better by AI than by real humans.
