No, even Hubble still delivers great contributions to science which are not quite matched by earthbound telescopes. Those win on aperture for sure, but Hubble is the only large telescope outside of the atmosphere. This gives access to wider wavelengths and removes all other atmospheric influences. That is the reason, the final passing of Hubble would be a huge loss, if not replaced.

There are several aspects we could improve on the current situation: make "better" telescopes or make more telescope. Having only 1, soon 0 space-based telescopes is cutting it very thin. Having 5-10 would increase our research a lot as more things could be observed.

Of course, eventually there will be a need for large space telescopes too, probably those will be enabled by Starship. But first we should use the currently available technology to make sure we don't fall back into the level of the 80ies when Hubble dies. And use modern technology to make this a "cheap" effort vs. the extremely expensive Hubble.
