Why Are ASICs More Vulnerable to Obsolescence than GPUs?

ASICs are designed for a single hashing algorithm, meaning their utility is entirely dependent on the continued profitability of that one cryptocurrency. When a newer, more efficient ASIC is released, the older model's efficiency (J/TH) is immediately reduced relative to the network, often making it unprofitable.

GPUs, however, can be repurposed to mine other algorithms or sold into the general computing/gaming market, giving them better residual value and flexibility.
