The article may be an oversimplification, but your comment is an equal oversimplification. There are many environmental conditions that need to be assumed when comparing reactivity.

For instance, if you have pure Titanium, pure Magnesium, pure aluminum in a vacuum at room temperature and proceed to introduce oxygen, you get the following reactions (simplified elemental chemical reactions, the Enthalpy of formation is what is important here):

Ti + O2 -> TiO2 (Std. Enthalpy of formation is -945kJ/mol)

Mg + O -> MgO (Std. Enthalpy of formation is -601kJ/mol)

4Al + 3O2 -> 2 Al2O3 (Std. Enthalpy of formation is -1675kJ/mol)

As a result, aluminum is most reactive, followed by titanium, then magnesium.

This is the reason why aluminum is used in solid rocket motors and various other explosive devices.

Under different conditions, these numbers may change: for instance a reaction with water instead of air may yield different enthalpies. At quick glance in water, titanium is actually least reactive when compared to aluminum and magnesium.

Having the CEO of Quora on the board also smells of a vested interest to hold the company/non-profit back.

Doesn't have to even be that complicated. Remember when YouTube comments used to be a dumpster fire?

I'm pretty sure YouTube is doing sentiment analysis on all comments and artificially promoting the ones that tend to be positive.

Yeah agreed. I'm a bit doubtful of the data presented in the article mostly because the company/CEO has a conflict of interest with objective analysis. They earn money from producing 'EV battery and range' reports.

The data in the article could easily be cherry-picked.

On the face of it, we don't know.

It's just he said she said.

I would partially disagree. I think your statements are true, but only for companies that raise investments on the promise of scaling to greater profitability, but ultimately fail to deliver. If the founders delude themselves or are overly optimistic, the only recourse they have to investors is to gouge the customer.

Raising the 'right' amount should be the goal. Not 'as much as possible'

If employee wages are a large part of the rising costs, then perhaps the cost of living for living in SF is too high. The cost of living is too high because rent is too high.

Since there is so much political contention to building more housing, there is no chance that housing prices will decrease (nobody wants to see their property lose value).

Now they are complaining about the problem they caused?!?

I don't know if this is ironic, justified or just funny. You can't have your cake and eat it too.

The thing is... Pushing outside your lane is VERY often discouraged. The manager sees that any time outside of your lane is less time in "your managers" lane, where you help buml his KPIs/goals.
