Irish Researchers Build DNA Molecular Computer With 100-Bit Capacity

The significance here is less about beating silicon than about a different trade-off: DNA computing trades speed for energy density and storage longevity, which is why it keeps resurfacing in discussions about long-term archival and low-power computation. A 100-bit ceiling and 25 sequential operations place this firmly in research territory, far from workloads that matter commercially today. The open question is whether scaling consecutive operations, rather than raw bit capacity, proves tractable — that has historically been the bottleneck for molecular computing.
