The computer.
Many older people on this site will remember the vagaries of linear recording and the time wasted with "punching in" and "punching out" sessions. How we used to pray for something easier to work with.
Be thankful for your non-linear recording capabilities. People have to understand the amount of power they have now in a home computer versus what professionals were using in the 80's.
Thank the software programmers, the chipmakers, the people devoted to making peripherals, that all have made it possible to have this revolution in music. The revolution where every person can now have a feasible recording alternative in their home.
Just understand how lucky you are now.
Sincerely,
God
