In November 2023, the code required to get this to compile and run was:

use std::{str::FromStr, time::Duration, collections::{HashSet, HashMap}};

use nostr_sdk::prelude::*;

use tokio::time;

const PRIVATE_KEY: &str = "PRIVATE KEY";

#[tokio::main]

async fn main() -> Result<()> {

let secret_key = SecretKey::from_str(PRIVATE_KEY).unwrap();

let my_keys = Keys::new(secret_key);

let client = Client::new(&my_keys);

client.add_relay("wss://relay.house", None).await?;

client.add_relay("wss://relay.damus.io", None).await?;

client.connect().await;

let message = format!("Hello, nostr! My public key is: {}", my_keys.public_key().to_string());

println!("{}", message);

let event = client.publish_text_note(message, &[]).await?;

println!("{:#?}", event);

// Retrieve only our last event (from both relays)

// let filter = Filter::new().id(event);

// Retrieve all the events that we have posted

let ids = HashSet::from([event]);

let authors = HashSet::from([my_keys.public_key()]);

let kinds = HashSet::new();

let generic_tags: HashMap> = HashMap::new();

let filter = Filter {

ids,

authors,

kinds,

generic_tags,

search: None,

since: None,

until: None,

limit: None,

};

time::sleep(Duration::from_secs(1)).await;

let events = client.get_events_of(vec![filter], None).await?;

println!("{:#?}", events);

Ok(())

}

I just asked "What is Truth GPT?" in Creative Mode.

Answer:

TruthGPT is a project that aims to create an AI chatbot that provides unbiased truths, as opposed to other chatbots that follow biased political agendas and hide sensitive information¹. It is also a cryptocurrency that rewards users for holding and staking the token¹. The project was announced by Elon Musk, who claimed he wanted to build a \"maximum truth-seeking AI that tries to understand the nature of the universe\"². TruthGPT has a mobile app and a web app that allow users to chat with the AI and ask questions¹. However, some people have expressed concerns about the accuracy and reliability of TruthGPT, as well as the potential dangers of powerful AI systems².
