Seen this so many times before.
You get folks that float on a air of positivity (mainly young people...hipsters...those just out of Uni) that think their idea will be totally original, have zero issues, cons, problems, set backs, cock ups etc.
Then there would be me at the back, the guy in his late 30's (now mid 40's) that is classed as 'old school', been there, done that for years and just gets constant eye rolls and teeth sucking noises thrown at him in meetings.
I would be the one that said " Well what if Google does this, that and the other..?" basically outlining all the obstacles as per the article.
Next meeting I wouldn't be on the list and that iceberg ahead would be getting larger and larger.
Oh well, kids eh?!
