At what point does a tool like Ramp's Stack replace QuickBooks or Xero as the actual ledger, rather than just automating on top of it?

One participant raised the recurring question of when these automation layers on top of the ledger actually become the ledger itself, noting the presenter had mentioned that eventually firms might not need QuickBooks or Xero at all. The concern raised was that companies may underestimate the work involved in migrations and the accountant's connection to the ledger, since a ledger is fundamentally 'just a database' but switching involves real friction. There was speculation about whether QuickBooks would absorb this kind of automation itself or whether Ramp would move to take over the ledger function. One view offered was that from a software strategy standpoint, it's hard to maintain a position of 'we're not forcing you out of QuickBooks, but you can move over if you want' for very long, especially given the high valuation pressure to expand market share. This was discussed as speculation and was not resolved.
