I referenced "Crest vs. Colgate" to suggest that quite a bit of marketing is a zero-sum game. If people drink more Pepsi, they'll probably drink less Coke. If they eat at McDonalds more, they'll probably eat at Burger King less. How much money do these companies waste shifting consumers between equivalent products?

I'm not against ad-supported businesses, but I'll bet Google would have made plenty of money off plain old search ads, probably enough to make Gmail free for everyone. If not, they could have charged a few bucks a month, or shown untargeted ads. In any case, they wouldn't have had an enormous database of PII, just waiting to be hacked or mined in more malicious ways when the ad bubble pops (e.g. credit reports, insurance).

Really[1]? We're paying hucksters 5-10x what we're paying teachers now. If that's what the market demands, then the market is twisted.

Anecdotally, my mom worked for P&G when I was growing up and she said the main difference between the brands was which one was on sale, sold more than the other. In a way the price was the biggest reason for selling toothpaste, not marketing.

Yes really. There's no rank of value. Go work on what you want to work on. Changing the value of teachers is a good goal and there are plenty of edtech companies being funded so if you care about it then go fix it.

I prefer that we all have the freedom that you can actually choose to do that, or not.

> There's no rank of value.

Wow... Thats cormac mccarthy level bleak but at least honest and I hope not to live in the world your labor may bring into being.

EdTech is mostly just a scam to siphon public school money to private companies. I'd rather just lobby my school district to pay teachers more.

It was an example, but you seem to be suggesting that some people have a more worthy cause than others?

What's the most "right" thing then and why aren't you working on it already? I assume curing cancer is somewhere on that list? Let us all know when you'll be getting to it.

Well, I certainly wouldn't put adtech in the same league of significance as space exploration.

And plenty of people wouldn't find any significance in space exploration, or whatever your career is. Subjective judgements are pointless overall. All that matters is that we have the freedom to choose.

> And what about all the other stuff that you get for free

It's only free if you think that the details of your life aren't worth anything (I specifically object to advertising targeted to individuals, I have no problem with ads similar to ones you find in a magazine or print newspaper).

Without any discussion, ad companies asserted that they have the right to spy on users and track them in almost every area of their lives online and off. I think we are finally starting to push back in the other direction. Europe has GDPR and I think it's only a matter of time before we have something similar in the US. IMHO companies should only be allowed to collect and use information on individuals in ways that each individual decides to allow.

> There's no "right" thing to work on.

But there are plenty of wrong things to work on.
