Digital computers much less capable than what we have today replaced analog computers as the standard numerical tool long ago; your improved analog computers would need to be *much* better than current ones.

The only "problem" with analog computers was the tube based operational
amplifiers required a LOT of circuitry to eliminate drift. Modern,
stabilized integrated opamps do not have that issue, which solved
that problem decades ago.

Finding precision multiturn potentiometers was somewhat of an issue
up until the late 70's when laser trimmed film potentiometers became
common off the shelf items.

The pen on the chart recorder, which always seemed to run out of ink
in the middle of a solution, is eliminated by an A to D  converter and
a PC.
