At least a finite countable lists worth, there's something for everybody really.

Some of us are satisfied with, say, dimensional reductions of spectral geophysical surveys to improve imaging and train that against existing production records to highlight potential mineral leases.

Others might like to leverage symbolic algebra systems to crack quantum encryption candidates.

A good number like to get rich via high frequency trading, some like to sail satellutes against the magnetic currents of the planet, there's a world of optimisations in logistics that have been implemented and are still being fine tuned to improve throughput efficiency and fuel consumption.

But you're not really asking in good faith here, are you?
