So, shortly, these are the important things to consider:
in some systems small errors grow to large errors;
our measurements cannot be completely precise;
there is some kind of randomness in physics (random collapse / indexic uncertainty of many-world splitting).
Therefore even the best possible measurement in time T1 may not give good results about time T2. Therefore exactly determining the future is not possible (unless we have some subsystem where the errors don’t grow).
Yes, that looks like a good summary of my conclusions, provided it is understood that “subsystems” in this context can be of a much larger scale than the subsystems within them which diverge. (Rivers converge while eddies diverge).
