2025 is the final RailsConf as we know it, per https://rubycentral.org/news/anewearforrubycentralevents/
I have been kinda of two minds on conferences - I've enjoyed a lot that I've attended/spoken at, but they are also in that sour-spot of being extremely expensive for people to attend yet still having to rely on volunteers for almost all the content and operations. Regional conferences should ameliorate that somewhat.
