How is possible that after YEARS of developing Adobe Pr still failing on such important things?

Guys how is possible with a 128gb ram macbook pro and premiere playback still terrible? Or i still have to use a gamma compensation to match what im editing with the export? like seriously.. Im a loyal customer since years and years, but im getting tired of dealing with bugs all the time, this editor job is already very frustrating at times, and WE the customers need a smooth workflow. Is insane that this bugs still here after years for the prices that we pay monthly. again INSANE.
