SAN JOSE, Calif. — A temporal physicist who successfully traveled back to 2026 from the year 2106 has expressed profound, lingering disappointment regarding the transition of modern automotive volume controls from physical rotary knobs to capacitive touch sliders.

Dr. Elizabeth Vance, presenting at the Silicon Valley Advanced Propulsion Symposium on Thursday, bypassed scheduled remarks on dark-matter containment to address what she termed "the dark ages of dashboard ergonomics." According to Vance, the historical record had not prepared her future contemporaries for the sheer, friction-free aggravation of trying to adjust a radio while driving over a mild road disturbance.

"We have digital archives of this transition era, of course, but experiencing it firsthand is deeply disheartening," Vance said, adjusting her temporal displacement harness, which hummed with a soft, stable blue light. "In 2106, we look back at the early 21st century as a pivot point for human agency. Yet, I rented a mid-sized crossover at the airport, and to lower the audio of a podcast by three decibels, I had to repeatedly tap a glossy, fingerprint-smeared piece of plastic while traveling at highway speeds. It is an extraordinary step backward for your civilization."

Local technology executives and physicists in attendance, who had gathered hoping to receive blueprints for clean energy or a unified field theory, reportedly grew restless as Vance spent 20 minutes demonstrating the input lag on a replica infotainment screen.

"We brought our entire research division to hear about the mechanics of the temporal fold," said David Sterling, chief technology officer at Altus Dynamics. "Instead, Dr. Vance spent a quarter of her slide deck showing us how a slight curve in the road causes a driver to accidentally crank the passenger-side climate control to maximum while trying to skip a track. She kept asking the front row, 'Who approved this? Where is the detent?' None of us had an answer for her."

According to Vance, the "Great Tactile Reclamation of 2064" eventually restored physical switches, heavy toggle levers, and weighted brass dials to all civilian vehicles, an era of manufacturing she now realizes was born of sheer, generational exhaustion. She expressed bewilderment that a society capable of engineering global satellite arrays would willingly accept an interface that offers no haptic confirmation of its own existence.

Before concluding her address and initiating her return sequence, Vance declined to take questions regarding future geopolitical events, stock market trends, or the outcome of upcoming democratic elections.

"I came back to warn you about the long-term stabilization of your orbital debris," Vance said, packing a series of glowing calibration rods into a metallic case. "But frankly, if you are willing to look at a flat piece of glass just to locate your hazard lights, you are already beyond my help."
