Mostly stronger mathematical guarantees and a cascade of results that currently depend on RH. The near-term builder opportunity is in tools that organize those dependencies, verify large computations and turn advanced number theory into usable infrastructure.
Optimization, planning, synthesis and parts of cybersecurity could change profoundly. You do not need to wait: products can already be built on today’s solvers and heuristics, with architecture designed to absorb future breakthroughs.
The immediate opportunity is not perfect weather prediction. It is faster, safer and more trustworthy simulation for engineering. A major proof could strengthen the theory behind those tools, but useful products can already be built today.
Collatz is less about a future industry and more about building better AI-math, formal verification and distributed mathematical-compute infrastructure today.
Mathematicians now know that some fixed finite gap between consecutive primes occurs infinitely often. The best unconditional published bound is 246, but proving that the recurring gap can be exactly 2 remains open.
