There is the show (which I don't share inviting candidates, other shitcoins, etc.) and there is the dev side (which we don't listen too much like lighting Splice, Mempool Acelerator, etc. The conference should invite politicians who are actually at power and announcing real decisions (like they did with Bukele as president announcing bitcoin as legal tender). They must also focus on devs and adoption.
i.e. it would be a very good presentation to invite MicroStrategy and make a report of the outcomes of their workshop recently organized with other companies inviting them to work with lightning network.
Another important thing is to attract AAA game developers and Microsoft/Sony/Valve to allow bitcoin on their platforms.
