Why do we still have daylight savings time?

Wasn't it created for farmers? Can't farmers just set their alarm clocks to match the sunrise?

As society became more industrialized, things like the beginning of school, work (for those with non-agrarian jobs), and public transportation were all synchronized by times, which were constant year round. For farmers who traditionally worked based upon sunrise and sunset, this caused their schedules to become mismatched with everyone else's at certain times of the year, so DST was proposed to alleviate that

That's only one of the reasons originally proposed for DST, though. Another was that adjusting the clocks so that it stayed light into the later hours of the day would reduce the need for artificial lighting and save electricity. This may have been true initially, but with the introduction of air conditioning into housing, more recent studies have shown that any electricity saved by reducing the need for lights is offset by needing to run the air conditioning later into the evening.

Finally, some people just argued that it made sense to have an extra hour of sunlight in the evening, after people had finished working, rather than to sleep through that hour in the morning.
