It's even worse than that. P2P means that connection differences between peers also makea difference. User A might see users B and C, but user B might on see A due to a connection difference between user B and C. It is very annoying to enter a group chat and hear:
User B: Is user C's stream dead for anyone else?
User A: I see user C.
User C: Sorry, what? I'm right here.
Honestly, other than a 1-1 chat, I can't think of a situation where p2p is worthwhile. Even then, it's almost always better to use an SFU.
P2P group video calls don’t work well unfortunately. Most people barely have enough upload bandwidth to upload one video stream. Needing to upload a stream per peer is a nonstarter for most people.
Sorry, but state is everything. If you don’t have state, then you’re essentially doing useless work computing an answer that is already known. Computation is only useful because of state.
What’s amazing about Dr. Suess is how much creativity and fun he packs into a very simply written book. Most children’s books are so asinine. “Sally went to the farm. She saw a pig. Sally can drive a tractor. Etc. etc.” There is rarely a point to the book. Dr. Suess uses similarly simple language: “You can think about red. You can think about pink.” While simple, the underlying message is usually profound, and that makes it so much more interesting.
I don’t know who in their right mind would want to be a teacher. Bad pay, hard work, ungrateful students and parents, and limited opportunities for growth.
What gives you the authority to define vernacular? Stated another way, words mean what people understand them to mean. Most people would understand crypto to mean cryptocurrency at this point, sorry. Cryptography is definitely more niche.
User B: Is user C's stream dead for anyone else? User A: I see user C. User C: Sorry, what? I'm right here.
