Without political will things will change more slowly. But they will change.
Most of the technology will come from the USA. But other countries will contribute.
Change will not be in a good direction and may make it impossible to ever have a manned deep space program in the US again for several lifetimes.
Also I wouldn’t be so sure the tech will come from the US as the tech lead we made over the rest of the world came from the Apollo program. Other countries, like China will re-create the Apollo program and face new hurdles which they will have to overcome with new tech - meanwhile, nothing happens in the US while China/Russia maybe India and Japan militarize the moon and Lagrange points. Leaving the US with nothing but empty dreams - such are the wages of radical socialism now sweeping the country.
