20 years ago the internet was less than 0.01% of global GDP. Tech will continue eating industries that are structured unfairly.
Like how tech took driving a taxi from a job that (unfairly) paid a living wage to one that doesn't.
While I'm not a big Uber/Lyft fan, prior to them the cab companies in the non-functional cities were atrocious.
I spent 40 minutes getting a bloody taxi at my lawyer's office in Las Vegas--and then had to wonder if I could get one back from the restaurant I went to. Getting from Monroeville to the Pittsburgh airport was a disaster. I can go on and on.
With Uber/Lyft in existence, a whole bunch of things don't happen with impunity anymore. Drivers can't refuse to pick you up. Drivers can't blow you off and not show up. Drivers can't refuse to take a credit card. etc.
Uber/Lyft aren't my favorite companies, but neither were the taxis.
Yes I know there are outliers but the vast majority of entrants are BSC grads.
Ironically, not only do tech workers aren't worried about this, they embrace it and encourage it. An enormous amount of work is being done to lower the bar, make things more accessible, reduce the need for diplomas and certifications, downplay the value of experience, etc. Basically ensuring that they'll see significant competition in the future (those initiatives don't help "a little". They literally change the landscape of the industry).
So it's a bit hard to convince people that they should work to protect their job when they're already working so hard to do the opposite (with the well being of others in mind, of course)
