Are Clone Ships a Better Alternative for Space Colonization?

...writing to memory.

Of human minds?

Where is a biosphere that can support even a single human for a decade?

Biospheres exist that support humans. Viable biospheres use nothing but known technology.
Yes, we haven't perfected them, but that's not due to a lack of any exotic physics.
I've said multiple times that current technologies will definitely need advancing and scaling up.

Where is even a fictional description of social psychology that doesn't end in near disaster?

That is a soft problem. Social psychology itself is not a technology that hasn't been invented yet.

Where is a practical Fusion Reactor? Those are the magic technologies that don't exist.

I did say "with the possible exception of a fusion drive".

A clone ship can work without them, A generation ship can not.

Except for one or two orders of magnitude in mass, clone ships have the same problems with interstellar-class propulsion.

Of the three, the social psychology "technology" seems the most implausible to me.

It's not implausible. We're not talking about how hard it is to do it right; we're talking about whether there is a path to it at all.
Social psychology, in and of itself is established even if it's got a long way to go.

I'm going to take a break from this for a while so that things can cool down. I suggest that you do to.

No, I'm good. I hope you are not reading any malice into my words.

I think clone ships a fascinating, worthy discussion about speculative science; I just think you're getting waylaid by trying to compare it to existing science. Let it stand on its own as a story idea and this whole sidebar goes away.
