The Wikipedia page highlights that there's certainly discussion, doubt and controversy surrounding those technologies.

The decisive factor of change I can see here is the unproven commercial viability of alternatives at the moment as Uranium is still cheap. Whether or not those alternatives become viable once Uranium prices increase isn't easily predicted.

So, I remain highly skeptical towars claims that dismiss the issue as merely a problem of "politics and lack of funding".

Did you read the part about breeder reactors above?

You can create fuel for the SMRs via a centrally administered and controlled (to avoid nuclear proliferation) reactor, so no need to worry about uranium... in fact, it might make sense to avoid the ecological impact of uranium mining anyway.

SMRs are being developed that use other fuels, too, that are available in abundance, like Thorium:
