How far off are we from being able to image an exoplanet?

Directly imaging an exoplanet has been done about 20 times (maybe more, by now). If you're asking how far are we from resolving an exoplanet to more than a single point of light, the answer is we will never be able to do that from this distance.

There are proposals to use the solar gravitational lens.

Failing that, you’d need thousands of optical interferometers larger than the Hubble spread across a distance wider than the Earth.
