My biggest problem with this: this effect does not affect only children. I see students learning to program giving up at the first syntax error; some don't even care about reading compiler messages and trying to fix them.

The first successful code I wrote was the following:

10 input a 20 input b 30 print a+b

I was around 12, without manual or online help and it was trial and error for an entire weekend until I got this right. Very few people I know today used to tech would have such perseverance.
