In addition to the issues raised by other commentators I would worry that someone trying to work on something they’re a bad fit for can easily be harmful.
That especially goes for things related to existential risk.
And in addition to the obvious mechanisms, having most of the people in a field be ill-suited to what they’re doing but persisting for ‘astronomical waste’ reasons will mean most participants struggle to make progress, get demoralized, and repel others from joining them.
The U.S. Federal Funds rate has been effectively 0% since April 2020 and was roughly 0% for six years from 2009 to 2015. The same is roughly true of the UK. Central banks in both countries are saying they’ll keep rates low for years to come.
I can’t immediately find a reputable business savings accounts in the UK/US that currently offers more than 1%.
Those that offer the highest rates (something approaching 1%) on comparison sites tend to have conditions (e.g. you lock the money up for a period, or have to keep depositing regularly), and usually have a maximum amount on which you can earn interest, a maximum which is low enough to be binding for these organisations.
These accounts usually offer a high rate to attract customers for a while, then dramatically reduce the interest rate and trust you won’t be bothered moving your money. I think that’s their basic business model.
Opening bank accounts for non-profits, at least in the UK, is a pain — something that will take a few weeks, and some time/attention from the operations team, management and trustees (who are needed for e.g. security checks). It looks like you usually won’t be able to put in more than a million dollars/pounds in any given account, often less.
So you’d need to open many accounts, keep track of them, secure the chequebooks, have them audited annually, integrate them into your bookkeeping system, change the signatures when staff turn over, figure out the idiosyncratic requirements to pull out money when you need to, and so on.
This may sound simple but if you’ve worked in operations you’ll know it’s actually a big hassle.
In return, for each account opened you make <£10k a year, and probably need to keep closing accounts and moving your money into new ones every few years, as the teaser rate used to draw you in is removed.
This may all be worth it, but it’s far from a no-brainer, as these organisation have other fruitful projects they could be using staff to pursue.
