Everyone should do their damndest to get 6 months worth of bills into savings. This should be easy for well-paid tech workers.
I've been making tech money ($200-250K) for about 5 years now, and my savings is enough that I could ride out a job loss for at least a full year with no change in lifestyle. With some minor belt tightening (I eat out WAYYYY too much), I could go 2 years before I had to start worrying.
