First generation seeking advice

I’m a 26 year old professional who moved to the Bay for work recently who works in Ops. Ever since I moved here, I’ve realized how much respect engineers receive because of the value they add to the company—especially since I’m in danger of being laid off. The future is relatively more secure and compensation is top of the line. Since I already have a degree in economics (non-quantitive focused) I am figuring out the least expensive way to break into this space. From my research, I’ve found the following pathways. 1. Free boot camps (Ex: Free-code camp, 42) 2. Online MOOCS and nano-degrees 3. Community college —> 4 year CS degree 4. Masters degree in CS 5. Coding boot camps If you have any advice or additional resources I’d really appreciate it!
