Are there nanites in our blood currently?
It may surprise you to know that the answers can't be found on the google search engine.
Wikipedia says:
The history of the mobile device has been marked by increasing technological convergence. Early mobile devices—such as pocket calculators, portable media players, satellite navigation devices, and digital cameras—excelled at their intended use but were not multifaceted. Personal digital assistants (PDAs) proliferated in the 1990s as a way to quickly write down notes, schedule business appointments, and set personal reminders, as a handheld supplement to bulkier laptops.

Mobile device and desktop were at the bottom of an entire page on wikipedia dedicated to the history of computers similar but equally misinformed to a youtube playlist on the same subject I am about to post and non-corroborative on to how our modern technology actually works.

So what's key here for the 1990-2000s modern development was the word "convergence" but it wasn't convergence was it? This was the culmination of a 500 year reverse-engineering attempt that began with the cylinder shot down in Germany 500 years ago. https://en.wikipedia.org/wiki/1561_celestial_phenomenon_over_Nuremberg
In fact you can look at any online explanation of this modern technology we use, and you can't find a direct descriptive or anything explaining why the components used to do this type of automation is so flat. Having designed it myself, I can tell you exactly why it comes out flat.
