Drawing from hands-on experience building Europe's first RISC-V HPC cluster (Monte Cimone), E4 Computer Engineering argues that RISC-V's main barrier to industrial adoption is no longer hardware, but mindset. The community must evolve from an ISA-focused culture to a full ecosystem vision: industry-grade CPUs and accelerators, robust OS and tooling support, a solid certification program, application porting, and active engagement with industrial users, ISVs, ODMs and OEMs. Only by combining a developer-first with a customer-first approach and actively listening to industrial users can RISC-V make the leap to mainstream adoption.
