Jae-heon Jung (정재헌), CEO of SK Telecom, reiterated plans to restore customer trust and improve services. He said the company ranked No. 1 in three major domestic customer satisfaction surveys for mobile services this year, and called the results meaningful after last year’s erosion of trust. Jung said SKT expanded field-based customer contact, strengthened AI-based security and spam blocking, revamped roaming and T membership, simplified rate plans, and broadened mechanisms to reflect customer input.

Agentic AX needs AI-ready data built first

Kim Ki-dong (김기동) of AI and data specialist Encoa said differences in AI agent results come from data readiness, not the model. He said many firms saw strong results in PoC and demos but struggled in real operations because legacy data lacks clear meaning, links and context. He defined AI-ready data as data AI can understand and trust. Encoa implements this with a “context map” and proposes semantic models and two graphs to find data and generate answers.

Tesla Cybercab has no hydraulic brakes. How does it stop?

Tesla has applied an electronic braking system with no brake fluid or brake lines to its production two-door electric Cybercab. The two-seat vehicle, which is known to have no steering wheel or pedals, also does not use a traditional hydraulic brake system. Instead, electronically controlled actuators at each caliper apply braking force to the rotor. Elon Musk said electric brakes reduce the complexity of hydraulic systems by eliminating vehicle-wide plumbing.
