Politics is an art of endless trade-offs; technology plays a vital role in shaping those trade-offs.
Choosing which directions to focus research on rather than relying on happenstance or the market is policy.
Therefore it all comes down to policy.
Note that your argument right now boils down to "we need to invest more in right technology"; while the decision is political, it's literally the opposite of what people mean when they say something is a "political problem" and not a "technological problem".
I disagree strongly. It's my belief that this attitude is a big part of the reason why we're not actually doing anything.
Depending on the poll and the degree of action requested, a small majority of Americans or a large minority supports climate change action. Policy action is very possible.
Agreed that political activity is really really hard and often fruitless. But when it's important enough we still have to try.
That I absolutely agree with.
Thank you for bearing with me and letting me figure out updates to my position on politics.
Then this should be what all of us are focused on because the future of humanity is dependent on getting everyone on board with this.
A country deciding to correctly price in environmental impact today would tank its economy on the spot. But availability of alternatives with lower emissions to various economical activities (e.g. electric cars as an alternative to ICE cars) allows that country to incentivize their use and offers opportunities to start pricing in emissions piece by piece.
The reasons why good solutions aren't implemented aren't always and only "because politicians are corrupt"; sometimes it's because they're impossible to push through (e.g. you'd lose election to someone who doesn't want to do this), and/or because going full-steam ahead risks social unrest and civil war, none of which will help climate.
Here's a breakdown of Polish fuel prices as of 2016:

TL;DR: price breakdown for Pb 95 gasoline: 39% net refinery price, 37% excise tax, 3% road tax, 19% VAT, 2% seller's margin. A carbon tax could presumably take the place of excise tax, but given that it's a big part of country's tax income, I think it'll have to be added on top.
As for acceptance, I'm somewhat surprised we don't have our own "yellow vests" - ask any Polish driver about gasoline prices, and you'll hear an angry rant about how expensive it is; mention a carbon tax, and they'll scream at you that >50% of the price is already taxes.
The story is very similar in all the other European countries as well. Countries that have a GDP per capita 2 to 3 times lower than the US are paying more for gasoline.
How about we make so much technological progress that removes our reliance on cheap carbon emissions that we can tax carbon emissions without affecting people very much therefore removing the need to get everyone on board.
If technology gets to the point where the cost of dealing with carbon is on the same order as municipal water and sewer it won't be a political problem.
I could burn my trash but my taxes pay the city to pay a company to come around once a week and collect a barrel from my house so why bother.
I drive ICE cars because in terms of results per dollar they're an obviously better deal than anything with lithium batteries. When it's no longer the economically obvious choice to drive ICE cars I'll stop doing it but not before then.
Note that this may happen with policy alone. Many countries and cities around the world are now heavily subsidizing electric cars, through things like tax breaks and waiving parking fees. This is only possible because electric cars are an available option.
What's that have to do with the technology?
Our climate-solving cocktail of 20 years ago involved things like drastic reduction of car use in favour of mass transit, and mass deployment of nuclear power to replace fossil fuel plants. We would be in much better shape today if that was done, but that set of solutions was (and still is) politically untenable - so technologists had (and still have) to invent different solutions, that are easier for politicians to implement.
There is no such thing as shifting from a "technological problem" to a "policy problem". Technology creates the landscape on which political choices are made. Where a problem cannot be solved due to political costs, technology can provide alternative solutions that are more politically tenable.
We may have a "cocktail of tech" ready for fighting climate change, but it's not of the right mix; it doesn't have the right political taste.
Getting Gates involved in politics? That's not without its own risks, and it may not be the best use of his time.
