Hey AJ

Thanks for this, pretty much agree with all of it. It seems like a week doesn't go by now without a new individual popping out the woodwork proposing an upcoming activation of CTV with no new PoCs and no new insights. I'm not sure what it is about CTV (versus say other proposals) that it keeps attracting these people that refuse to work on PoCs or anything that drives the research area forward and yet want to try to attempt activation where the success scenario would be a chain split.

It is hard to discuss APO in a vacuum when this is going on the background but I'm interested in you grouping APO with CTV in this statement. At the time of writing there clearly isn't consensus or advanced PoCs on any of the use cases CTV claims to enable. (One rare exception on the use case front is James O'Beirne's OP_VAULT [0] that requires additional opcodes to OP_CTV). But APO does seem to be the optimal design and have broad consensus in the Lightning community for enabling eltoo/LN-Symmetry. Any other use cases APO enables would be an additional benefit.

I don't think one can seriously think about an *upcoming* activation for APO as there is still more work to do to convince the community that it would be worth the risks of embarking on another activation process. But assuming another year of concerted work on APO and the CTV woodwork of chaos (hopefully) being exhausted do you think an APO activation would be viable in say 2025/2026? Is your hesitancy on APO based on any particular technical concerns or just fatigue from the CTV chaos?

Thanks
Michael
