It's 'legit' to feel a certain way, the opposite to make decisions about business and productivity that way.
The real trick is, to figure out all those things we do that we think are based on utility, but are not.
The Saab ad comparing their car to the Jets the make appeals to our 'every little boy wants to be a pilot' fantasy.
But the Ford ads that tell us how 'strong' our vehicle is going to be ... even though many of us will never, ever use them for this purpose.
Like the guy with 1000 different tools in his shed - he buys them 'because they are useful'. But really, it's the 'emotion/novelty' of utility, not actual utility.
At least 1/2 of the tech industry is driven by this, it's hilarious. We HNers, so neurotically passionate about whatever it happens to be ... are the most guilty.
Of course a lot comes out of purely speculative and creative use of technology, it's just that we should be better at discerning.
Slack, if it's bad, is probably because it's a noisy channel, not because it's Salesforce.
