Content
The launch of the Gaia mission has paved a way to millisecond-scale optical position measurements, reaching and exceeding accuracy attainable by radio VLBI. These advances do not make radio astrometry obsolete. Instead, multiwavelength measurements open fundamentally new opportunities, impossible with either VLBI or Gaia alone. In this talk, I will explore these opportunities and implications for further astrometry improvements, as well as for probing AGN physics. I will highlight current results and upcoming studies on the jet properties and the disk-jet connection. The near future will bring an even tighter VLBI-Gaia synergy, especially with new Gaia releases and variability measurements.
