Bot web traffic has overtaken human web traffic

I've been seeing this claim repeated across social media, blogs, and various online communities these days. However, I haven't yet found a discussion that digs into the evidence behind it or provides reliable sources.

Where can I learn more about this topic?

I'm increasingly skeptical of mainstream media coverage and a lot of what I encounter online, so I'm looking for sources that are as rigorous and unbiased as possible. I'd especially appreciate:

• Academic papers and research studies
• Industry reports with transparent methodologies
• Independent analyses that critically examine the claim
• Any insights from people who work in web infrastructure, cybersecurity, search, analytics, or related fields

If you know of high-quality resources, I'd love to read about them.
