Thanks for this thread, Bob, it's really enlightening. I realize you're swamped now with questions, but I'm curious about a few things and forgive my highly limited understanding of technical concepts so some of the questions might not even make sense (if so, just ignore):
1/ If Ripple are serious about making XRP a global bridging/settlement asset, how are they planning to lift the relatively low ~1,500 txps limit to on-ledger scaling?
2/ (a) Do you know much about Elixxir (Chaum's latest endeavour, backed by Larsen) and if so, can you comment on it i.e. its supposed potential to scale "limitlessly" using pre-computation methods? (b) Could Ripple hypothetically "borrow" some tech and even upgrade the XRPL if it was proven to scale as per the claim, or are the technologies just too different?)
3/ How far can the DEX concept go? For example, I don't really understand what having trustlines over ILP means, but I've heard it mentioned, and you mentioned ILP accounts. But what's the account "on" if it's just over ILP? If you can decentralize exchange of value via Gateways on XRPL, and Ripple pivoted to ILP bank ledgers instead of Gateway issuances, could we just end up with a kind of ILP-DEX using XRPL as a "hub" for distributed orderbooks too? (Sorry if that's a dumb Q for obvious reasons I can't visualize).
4/ Riffing on the above, how much dev time went into autobridging, synthetic orderbooks and so forth at Ripple; was it abandoned or ever end up in commercial products?
5/ I imagine Ripple sort of ending up like a Google for payment routing, with a hub model. I guess one could theoretically decentralize search, but in practice it wouldn't work well because centralized governance leads to focused innovation. Ultimately do you see XRPL becoming an automated hub for payment searching/routing over an ILP global infrastructure, a bit like Google is a hub for searching data?
