20. OOP  is  about  taming  complexity  through  modeling,  but  we  have  not  
    mastered  this  yet,  possibly  because  we  have  difficulty  dis9nguishing  
    real  and  accidental  complexity.  
    I  believe  that  to  make  further  progress  we  must  focus  on  change  and  
    how  OOP  can  facilitate  change.  A#er  all  these  years,  we  are  s9ll  in  the  
    early  days  of  OOP  and  understanding  what  it  has  to  offer  us.

    11.6 seconds on average in May of 2011.

36. “SQL  databases  are  fundamentally  non-­‐scalable,  and  there  is  
    no  magical  pixie  dust  that  we,  or  anyone,  can  sprinkle  on  
    them  to  suddenly  make  them  scale.”
