One AI Bottleneck Workaround: From the WEF No Less
June 5, 2026
The World Economic Forum discusses the barriers AI is finding when it comes to development: “AI Is Hitting A Wall. Here’s How We Rethink The Hardware To Break It.” When AI models grow larger that more time and energy needs to be spent moving data between memory and processors. It’s called “memory wall” and language-processing model grew 5,000 fold in size over four years.
Memory wall is a problem because large scale AI systems are increasing. This drives up costs and infrastructures. A second reason is that many valuable AI uses rely on fast decisions made locally instead of the cloud. Medical devices, autonomous vehicles, rescue drones, and more can’t rely on sharing information with data centers and waiting on responses. They need hardware that makes the AI more practical.
There are ways to overcome the AI memory wall bottleneck:
“…there are three main ways to ease this bottleneck: move computation closer to the data, draw on the brain’s event-driven information-processing method and use lower-precision or stochastic computing where exact arithmetic is unnecessary. Together, these approaches could support a new generation of AI hardware that is faster, more efficient and better suited to large-scale infrastructure and edge applications.”
These three options are the most powerful when they’re part of a single design solution. AI hardware that is designed in the future can’t rely on a single chip then fitting the algorithms on it as an afterthought. They need to be considered as part of the architecture during the design phase. Here’s what should be done:
“That is why hardware-algorithm co-design is becoming so important. Some workloads may benefit most from compute-in-memory; others may benefit from spiking networks and event-based sensing; and still others may rely on mixed-precision or stochastic methods. In many cases, the best solution may combine these approaches on the same platform. The larger implication is that the future of AI depends as much on hardware design as on model design. More efficient AI hardware could help contain the growing resource demands of large-scale systems while improving the safety and reliability of devices in the field.”
Interesting. But what if there is something other than the Google Transformer-centric method? The WEF will pivot, of course.
