This doesn't make any sense. ASIC's take tons of time and money to design. Unlike blockchain, where the PoW algorithm is part of basic compatibility, it's not at all in mcaptcha - the users see a checkbox. The rest is implementation details. If someone creates an ASIC, you can break it very easily by changing the PoW algorithm a bit, and no users are affected. Even if someone has the money to keep up with you, which is remarkably expensive, they will be too slow right now. That would be hard to change
