The scientific method goes boing.

1. Form a question.
2. Observe evidence.
3. Form hypotheses.
4. Create experiments.
5. Observe results.
6. Compare hypotheses.
7. Be critical.

The scientific method runs off the rails in step 2 and explodes into uncertainty in step 3. It turns out that observing evidence is rarely easy or straightforward: it's a great big universe, and we're all really puny. And "forming hypotheses" is synonymous with "make guesses" -- potentially educated, informed guesses, but still a creative process that is likely to baffle AI for decades to come.

That brings us to today's problem: why does Netflix hate me?

If a previously reliable gigabit connection is suddenly working at 100 Mb/s, you probably have a flaky cable. Replace it. Yes, I know it hasn't moved in months or years so there can't possibly be any mechanical stress. Kill it with scissors.
