Gist if you don't want to read all that:

- Bitcoin/LN is not needed. LN is pretty easy now.

- Nostr is actually decentralized.

- The system set in place to find people needs to improve, can and will.

- Biggest issue is actually server load and how to handle running costs (this is a servers issue, not a nostr issue. Still needs to be solved though).

- Nostr can't ban you (a nostr relay can, but can't ban your account, your followers, your follows, etc).

- Pub keys as usernames are an issue yes and NIP-05 isn't a good solution.

- Some nostr clients will have ads.

- Spam would be handled by relays, clients, and users. Freedom comes with the cost of responsibility, and the results will be better than centralized.

- For current relay related issues, a potential solution is for relays to start talking with each other and be P2P for each other in some parts.

Note: I appreciate him attacking nostr so that we know where flaws are at and improve it, however, it seems like this person is adamant about the supposed high likelihood of nostr dying in around 5 years, without seemingly delving into nostr directly and checking it out (from the looks of it / from how he pointed out a couple of things, which also resulted in him misunderstanding points and not being up to date with how things have improved. This video has mostly, not entirely, wasted my time. (no slight for you posting it, all's good x3).

1 - Getting a non custodial LN want with funds (so decentralized) is pretty easy nowadays with Phoenix and Mutiny (plus nostr doesn't need bitcoin or BLN).

2 - Telegram link: It's not that deep, it's just ease of communication currently for more people to get involved.

3 - Alice is on relay A, Bob is on relay B, they can't see each other. What can be done here is, perhaps through a new NIP, relay A can look through its users' metadata and see what relays they have on them, ping said relays to find Bob, Bob would show up in search for Alice, and one of Bob's relays would be added to Alice's connected relays.

4- All popular relays censoring you from writing, you can still read of course, but of course they can't delete people that already followed you, or you them, and can't stop any future event of this kind, which is already massively better than Mastodon. However, going back to the main issue, I don't think it's that big of an issue because if people still want to hear you, they'd just add the relay you'd be on, and as time passes, users wouldn't have to worry about adding/removing relays as that will happen in the background automagically by clients. Plus, relays wouldn't have the pressure issue like what Mastodon has, pressure from other servers to ban people otherwise they wouldn't connect with them. The power is with the user, not the relay operator.

5. He mentioned that the pub key is somehow centralized, later on he reversed that statement.

6. The note about how the nostr site is saying that nostr doesn't have ads in comparison to twitter, I'm in agreement and disagreement here, because yes, technically it doesn't on its face, however, there are "zapertising" on clients at the moment, and clients will eventually add ads to their clients if they desire to.

7. On the point about when there will be a huge number of users on nostr, like mainstream level, relays from your average joe running is server in his house will probably not be able to handle all this pressure, resulting in those relays shutting down or adding a paywall / pay as you text, and the whole experience on nostr will be really slow. My view on this that yes, there will be free and slow, paid and fast with how things are, and thinking with a better solution in the future is what's mentioned in point 4 above, with the addition of if one relay is pressured and another is not, writings will be redirected to the available relay and a user's account would have that new relay attached to them. Basically, the relays become P2P with each other, not users/clients, and aside from that, to help fund servers, relays would have free and paid versions that prioritize the speed over others. Another solution to decrease this issue is having micro relays in each client that stores the users data, accessed by others as first or backup to relays, if it's available (so hopefully that would decrease pressure or at lease increase some reliability with the whole experience).

8. nostr: "twitter... keep you addicted" yea i don't see the point of this (ish), guy has a point, and that is a nonpoint / clients can do this too if they want so moving on.

8.5: eh, i want chronological, but i can see the benefits of algos, so hopefully clients push and provide both (toggle / separate tab maybe for the algo)

9. twitter bans people "so does nostr" is not correct. Nostr cannot ban you, you can still speak, and you can still get your own data if you've backed it up. That is just a false statement. A correct one is "nostr can't ban you. A nostr relay can ban you."

10. on the nostr having spam: yea there will be spam, although because of the nature of how nostr is operated at, the relay, the client, and the user will all play a role in handling spam. With freedom comes responsibility, and the results will be a shitton better than how twitter or any other centralized service would handle it.

11. The issue with npubs not being user friend is a valid one, and NIP-05 isn't a good solution for the nature of nostr (even if you self host because of the ICANN problem). This is actually a solid problem imo.

12. nostr: "there are no clear incentives to run servers" (towards mastodon) youtuber "same with nostr", ya, true. so this is a non-point
