I think a lot of this churn can be sidestepped if you avoid startups and instead work for an "Enterprise" organisation. everything is much less cutting edge. In fact technology progression is pretty much glacial. If you look at what technology was popular 10-15 years ago then that's what will be in use in Enterprises now. Java web services is currently the big thing at my company. All the late 90's business apps which were in Visual Basic, Oracle Forms and Access are being rewritten as Java web services at the moment by an army of contractors. In another 10-15 years they will be rewritten again in the language Du Jour of today probably Go. It's an endless cycle.
