No one can predict the future. The best way to predict the future is to create it as Andy Grove said. But I've seen so much technological innovation in so many areas that have solved so many problems that were considered intractable. Remember "The Population Bomb?"
I don't think government involvement is always wrong but we put too much emphasis into letting the government deal with solutions, many which fail. It also let's us off the hook for making the necessary changes.
I think the private sector has done a better job of reducing CO2 emissions than the government has over the last 10 years.
I also believe the right way to solve climate change is for the private sector to create products and solutions that get people to change their habits and lower their carbon footprint. Tesla is a good example of this. Government does help in kicking this off but it should get out of the way and let capitalism do its magic.
The population bomb is still armed and ticking. Birthrates are dropping worldwide, but it's too little too late. The human population is larger than the long term carrying capacity of the planet and that is the core driving factor of most of the world's ills right now.
Corporate players can be more efficient, but at the end of the day corporations are beholden to their owners, not the public. If the needs of the general population and the needs of the shareholders diverge, the company is obligated to side with the shareholders unless they are up against a black letter law made by the government.
A number of individual companies doing things doesn't have the coordination that a functioning government can have. The problem is that thanks to the Republicans completely forgetting how to govern, the US has not had a fully functional government in a couple of decades.
One of the insidious things the right wing propaganda machine does is convince the public both parties are equally incompetent at governing. The Republicans bumble around and break things and the propaganda machine convinces those who aren't brainwashed that the Democrats are just as bad at governing. So people lose faith in all the institutions of government.
Government is not often the most efficient way to get things done, but it actually can be much better at projects that are going to take a long time to complete and cost a lot of money up front. The US has the interstate highway system because of a plan drawn up in the Eisenhower administration that took more than 30 years to complete. Los Angeles was only able to become a large city because of massive water projects to bring water from other places to Los Angeles. There projects required initial investment way beyond what any company could handle and took decades to pay for themselves, but they vastly improved the country in many ways.
By the 1930s the electric grid reached most larger cities, but rural areas had no electricity. It was not cost effective for the utilities to run power lines to low density areas. FDR fixed that. We badly need a similar program to bring high speed internet to rural areas, but people are too convinced the government can't do anything, and with Republicans in charge it can't.
The tech industry has brought a lot of good to the world, and it had less help from governments than a lot of other industries, but not all industries have the built in advantages that allowed the tech industry to do that. And there are lots of things the tech industry isn't doing that somebody else needs to step in to do (like high speed internet for rural areas, or just fixing bridges that are about to fall down).
And I know some Silicon Valley companies make hardware. Cisco is one, HP and Tesla are other players making physical machines, but quite a few are just making software. I work for a Silicon Valley company that makes hardware. I believe I am the only software developer in the company. Definitely the only one developing software to run on their products. They may have some web code writers in a backroom somewhere.
And Trump seems to think Bevin won by 15. The bunker scene is coming soon.
