I find this laughable because it's almost the opposite of the "If we can put a man on the moon, we can solve cancer." fallacy. If we can't copy an amoeba, we won't. LOL. No? I beg to differ. We can't right now, and for a million fundamental reasons that are all being solved in time.
Here's some perspective. I work in cell biology. 3 years ago, genetic expression required measuring the RNAs of at least a small cluster of cells. Two years ago, single cell RNA analysis became available. A year ago we started seeing the ability to split one cell into 4 equal vessicles, each able to be analyzed separately if need be. We also now have the software and processing power to infer huge bioinformatic hypotheses from this intricate data. In three years the ability went from an average, to a single, to a greater sampling number from the single (for statistical accuracy). THIS IS NOT EVEN THE UPCURVE OF SINGULARITY, but it sure feels like it.
Nanomaterials are allowing for crazy new properties on the macro-scale. Biotechnology is becoming cellular an surpassing simple chemistry. Artificial intelligence is now being implemented on neural-like computer architectures which are much more powerful at brain-like activity.
Full Disclosure, I've been a Kurzweilian Singularity Believer for years now and my life is betting on it. But I've had a lot more than confirmation bias going on to keep my confidence very high.
