Thanks for sharing about you. 
You said you are about 50 years old.  Do you not worry about ageism in Bay area ?  
I just turned 30 ( 4 months back ) and I feel that at some point people start seeing you differently.<p>Have you ever had chance to move into management role ?  Did you accept ?  If not, may I ask why ?<p>I am trying desperately to move into management role but my current company is very large and there is not much opportunity.<p>Any advice you could provide for this fellow developer on how do you see 25 yrs old making similar or at sometimes more than you ?  How do you get younger ( or most ) people respect you ?
What is your reaction when someone act like they know all world?<p>Thank you.
