Anthropic's claim that its AI can clone enterprise apps like Slack highlights a shift in software development, where the focus is moving from assembling frameworks to describing intent, thereby lowering the barrier to building complex applications. However, the challenge remains in running these applications efficiently at scale, especially when faced with high user demand and various technical constraints such as data residency and real-time event handling. Infrastructure services like PubNub become crucial in ensuring speed, reliability, and compliance, providing the necessary backbone for applications to function seamlessly across global networks. PubNub's extensive infrastructure supports message delivery with low latency, secure data handling, and compliance with regulatory standards, enabling developers to focus on enhancing user experiences rather than managing operational complexities. As AI reduces the time and cost of software development, success will depend on the ability to operate these applications efficiently, ensuring they are responsive, reliable, and compliant across regions.
