No not at all. I've watched you tube videos on repair of a tub faucet, brake repair on newer cars, or converting a 62 amp blade server power supply for normal hobby use.
I might watch a purchased tape or DVD of trains once a year. Those i can easily stop and restart as desired. Plus there is a certain level of quality and perspective.
My grandson and i go and watch real trains about twice a week. There you can be as close as you want, if you need the "experience".
