Adrian, Jason and John have had a long discussion on this subject.
I asked Kimi K2 Thinking AI to summarise the differences between these
theories.
(Hoping to add some clarification).

Kimi K2 Thinking AI -
Here’s a detailed breakdown of why most physicists prefer the Many Worlds
Interpretation (MWI) over superdeterminism, despite both being
deterministic theories:

## Bottom Line: The Consensus Preference

MWI is preferred because:
1. **Preserves statistical independence** (the bedrock of experimental
science)
2. **Avoids cosmic conspiracy** (no need for fine-tuned initial conditions)
3. **Accepts only "tame" non-locality** (no faster-than-light causation)
4. **Maintains scientific method** (experiments test real hypotheses)
5. **More parsimonious** (uses existing mathematical structure)

Superdeterminism, by contrast, is seen as a **desperate loophole** that
"undercuts the whole scientific method"  to avoid admitting quantum
non-locality. While not definitively disproven, its cost to scientific
epistemology is considered too high
