It seems the purist definition of solving protein folding means specifying the sequence of actions to arrive at the native structure for a given input sequence. This implies your solution is grounded in a physical reality. Such approaches (i.e MD simulations) have not been very successful to my knowledge and are computationally intractable for most proteins. Even if you are able to do this, how do you verify that your folding mechanism is in fact correct? We don't have ground truth experimental data at the temporal resolution one would want to verify such a prediction.
For now, the only practical framing of the protein folding problem is to predict a native structure given an input sequence. This is simply because we have the requisite data...
Agreed. The authors already made up their mind regarding the conclusion before writing the paper. This is an analysis that should be done by a group not involved in aging research so it's 'unbiased'.
Also, I think it's important to appreciate that the formation and growth of Silicon Valley was a remarkably special thing but was bound to eventually hit the diminishing returns phase of faster compute, faster internet, smarter software, etc. Silicon Valley started with a transformative and enabling technology (the transistor) and from there we built a remarkable hardware and software ecosystem over the span of a few decades around that technology. Those seem to be the two elements in order to 'replicate' SV: a transformative technology that spurs an ecosystem of technologies, all of which interconnect and benefit from each others innovation.
