not from fly.io, but my experience is that most data scientists will just prefer to lump it with the tools they know (pandas / R) on CPUs, rather than delving into things like rapids https://rapids.ai -- even if it makes things faster/cheaper.

I might have had a bad sample set so far. But the "doing statistics" bit seems to be the interesting thing for them. the tooling doesn't really factor into solutions/plans that often. and learning something new because "engineer say it shinier" doesn't really seem to motivate them much :/
