Schnorr’s result showing the convergence between prefix-free Kolmogorov complexity and Martin-Löf randomness is very suggestive. As has become clear, the existence of other notions of randomness—incluing Schnorr randomness, as well as a number of other proposals (Li and Vitányi 2008: §2.5; Porter 2016: 464–6)—shows that we should be somewhat cautious in yielding to its suggestion.
