The message you just wrote involved how many complex systems, from your keyboard switches and firmware to your BIOS and OS interrupts, to your browser, the internet and middle boxes, just to say one sentence to someone. It would be much simpler (and more secure!) if you just told me with your mouth, but you didn't do that.

Of course, and if you use all these services you can be a pedantic ass who never has to actually ship a product.
