CPU → GPU → FPGA → ASIC
The first miners used central processors. Graphics cards handled parallel operations better, FPGAs offered more flexibility, and ASICs made it possible to build a chip optimized for one algorithm.
Each transition raised the barrier to entry. Today, competitiveness depends not only on chips, but also on electricity, cooling, financing, logistics and risk management.
What could shape the future
Potential development paths include more efficient chips, the use of surplus and intermittent energy, heat recovery, flare-gas utilization, flexible load for power systems and miner diversification into HPC and AI.
That does not mean every ASIC will automatically become an AI server. But infrastructure, electrical connections and energy-management skills may have value beyond mining itself.
