Prove me wrong. That's the point to a discussion. You share points of view. But if I follow your path of discourse, I could just say you're a sheep that'll believe whatever silicon valley tells you.
However, I mostly argue that the taxpayer cost doesn't justify the gains. It's expensive and most counties and cities have to foot the bill or heavily subsidize it. If the telecom company wants to foot the bill. Good on them. No arguement here. If the city has to, go fuck yourselves. Its diminishing returns to a ridiculous level.
Really we have no idea of the the doors it could happen. In the 90s many people thought the internet was a gimmick or a fad. Today the most successful companies are built on it. It's very likely the same will be true for 5G enabled technologies and companies.
5G is not a revolutionary tech when we already have wifi and 4G.
