Great article Dan. This is slightly off-topic so perhaps you won't answer it here - It is unclear to me what utility KSM and DOT will have in the ecosystem beyond being the bidding currency in the parachain auctions, staking and governance. Is it the case that they will be the gas for all transactions (although it is low-gas)? Is there other utility - e.g. in the same way that ETH and BNB are the most liquid tokens in their own ecosystems? For example, will users require KSM / Dot to use Acala and Karura? Thank you for your great work.
