50% chance. Got a bit of interest in the 2031 market with a generally low probability estimate in the first few hours, so here's one with a longer timeframe. DNA has a very high information density, and methods for random access have been improving. https://www.researchgate.net/publication/370524323_DNA_storage_in_thermoresponsive_microcapsules_for_repeated_random_multiplexed_data_access Will this be in use by 12th February 2035? (Deliberately setting a random mid-month date to reduce end-of-year resolution spikes.) By "in use" I mean either you can buy it for a not-completely-unaffordable price, or, more likely, there are credible reports that a company is using it for non-gimicky reasons. So I require not just that it's possible, but that it's moderately practical. As both of these are somewhat subjective, I won't bet in this market. If anybody has an idea for making one of the above less subjective, I'd be interested to hear it. Early bettors, beware that I might add more specific criteria in line with the spirit of the question. I'll give a chance for objections if I do.
