I've had 5 jobs now, each lasting about a year and a half at most, and I only quit 1 of them because everyone on the team was being replaced to avoid having to grant any options prior to an acquisition. Twice my employer went out of business entirely, another time they laid off 20% of their workforce to secure more funding, and most recently a company let go all of it's remote developers after a change in leadership. While I agree you shouldn't quit your job without having the next thing already in place, at least in my experience this is a very volatile industry and you can't really expect to keep a job for a long time anyways. The odds may be better at a bigger company, but it still happens. One of the largest employers in my city just laid off about 1100 people. I've been lucky in that I've been able to quickly find work after these things happened before, but I look at it like I need to be prepared to potentially have to go without work for months at any time. Hopefully my next job will be one I can keep for several years, as the constant job hopping really isn't for me.
