What are the similarities between ancient methods of transmitting information and modern methods of transmitting information?

I think there are the following aspects:

1, which can realize point-to-point and point-to-point information transmission. In ancient times, the typical flying pigeon spread books to realize the transmission of information from one person to another, and the beacon tower spread smoke to make one party's information known to many parties; Modern mobile phone calls have realized one-to-one communication, while mobile phone short message group sending has realized one-to-many information transmission.

2. Information transmission needs to rely on information transmission media. Whether in ancient times or in modern times, information transmission depends on certain media, such as flying pigeons that deliver books in ancient times and mobile phones that deliver information in modern times.

3. The object (information content) carried by the media is sensory impression. In other words, the object of communication is visual impression or auditory impression; Ancient flying pigeons handed books and conveyed visual impressions (words or pictures, etc.). ), while ancient people sent messages to distant relatives to convey auditory impressions (sounds); Modern people's mobile phone calls and short messages also transmit auditory information and visual information respectively.
