@rek it's actually dangerous to not do VHF. Most of the northern baltic sailors I know only use radio though they toy with other tech. The necessary immediacy of radio proximity is like a rope, or a harbour. But then, I only know pretty old sailors (avg. 60+).
@poetaster When we did our run around the Pacific Ocean, ppl were using their radios, as did we, but many ppl had SAT messaging. I didnt get a sense that ppl werent leaving radios on. Bit different now with Starlink. All sailors that I know that are going offshore in the last 2 years have it (whether or not that means theyll use radio is something else, id have to ask how often they leave it on).
