> The problem is that, at same time I feel that coding can't be a lifetime career: what will happen in 10 years from now? Maybe company will prefer younger coders to hire and I will not be able to find a job anymore? What will happen in 10 years? Who knows? Things change a lot in 10 years and your perspective on things will change too. I think you may be overly stressed about ageism (keyword being "overly"). All of these young engineers will hit their 30s/40s/50s/60s too and the age group distribution will reflect that in the years to come. I'm in my 40s and most engineers I socialize with are my age or older. None have any intentions of becoming managers. Keep a level head on HN, the attitude here is very SV focused and doesn't necessarily provide an accurate depiction of the overall industry.
