This is a reality check regarding Geoffrey Hinton's recent alarming warnings about AI advancing faster than expected. Having used all frontier models extensively in my daily work, I believe his worries are misplaced, mainly because he overvalues LLMs' abilities. The supposed exponential AI advancement we were promised simply hasn't materialized. Below, I summarize the key points of a longer article. You can read the entire article here: Hinton’s AI Progress Illusion: An IT Reality Check.

Microsoft Entra ID introduces synced passkeys to simplify multi-factor authentication and reduce the security risks associated with traditional methods such as passwords and SMS codes. This feature, announced at Microsoft Ignite 2025, enables users to authenticate with biometrics or device PINs without entering passwords when syncing credentials across devices via cloud-based passkey providers. The implementation also includes high-assurance account recovery using government-issued ID verification to restore access when users lose all authentication methods.

Organizations running modern data centers increasingly need flexible storage architectures that balance performance, resiliency, and investment protection. With Windows Server 2022 and Windows Server 2025, Microsoft now enables true S2D and SAN coexistence—allowing Storage Spaces Direct (S2D) to operate alongside traditional SAN storage within the same failover clustering environment. This mixed-storage approach lets IT teams optimize workloads such as Hyper-V, SQL Server, and file services by combining high-performance local storage with existing enterprise SAN infrastructure, all while maintaining full cluster support and operational consistency.
