Should you be less or more worried? Good question.
The simple truth is the VIX spike will come at some point. We all know it. It's not matter of IF but matter of WHEN. But the WHEN is very important here. If you just go long VIX (via futures or one of many existing ETFs), you need to be very good with your timing, otherwise VIX contango will work against you and the position will slowly bleeding money.
My biggest mistake in 2017 was trying to time the VIX spike. When VIX went below 11, I asked "how low can it go and how long can it stay there?" Guess what - it went to 9 several times, and it stayed below 11 much longer than most people expected. I got it right couple times, but overall it was a losing proposition in 2017. I also rolled some of the trades few times, but when you roll, most of the time you do it for a debit - again, due to contango (more distant futures are more expensive, so the options are more expensive as well).
As they say: the market can stay irrational longer than you can stay liquid.
