I don't think async can make things faster but it can make them more energy efficient and the incentives for that is still close to none as our economic models reward waste until all EROEI is depleted. But you need to add the ability to switch things off dynamically, meaning cores on CPU/GPU; so far the industry has solved this with little.big but that requires all software to change, it's going to take time that we unfortunately do not have as hardware is closing the ownership model.
