Scalable? Not for same-day. I'd be fine waiting a few days if needed, though. Heck, early voting means I wait for weeks now.
Ranked choice voting is essentially doing multiple elections at a time, having to recount portions of votes every time a candidate drops out. That's a lot easier with computers.
I think the totals from every precinct could be made public in a way that they are verifiable from a central database, where the numbers add up to the total for the state and eventually federal count.
This is probably already happening, but people don't seem to think so.
Same-day? It is not a problem at all. For example Finland calculates enough paper ballots in hours to give a definitive result, I am sure there are other countries that manage it as well. Your imagination is stuck in the world of voting practices of your side of the pond.
