They're not really after biological age, they're after psychological readiness really.

A simple and purpose-oriented solution would be a quick sexual health quiz prior to entering adult websites.

@vandys @clacke

Yes, Matrix uses Jitsi for that as far as I'm aware.

No need for disclaimers, that makes you even more interesting participant in the discussion as an industry insider :) Environmental activism somehow turned the debate upside down implying that if you work in the industry and know anything about technology, then you must have vested interests and should be distrusted - so at the end of the day only people who have no clue about either are allowed to take part in discussion 🤦‍♂️

@freemo @2ck

So just to summarize the thread: I'm generally a supporter of wind and solar assuming their physical limitations are honestly accounted for just as we do with any other energy source. Wind and solar aren't silver bullet, they aren't made of pranic energy but from mined materials, they fail, burn and pollute environment just as any other man-mage machines.

@JFK_NOSCOPEZ_420 @freemo @2ck

Many brilliant ideas and innovations out there, but engineering challenges and economy usually render many of them impractical. Sea is a quite hostile environment for any engineering project due to tides and salt. And the further you move storage from the consumers, the longer transmission lines you need.

@freemo @2ck

Speaking specifically about wind turbines, they are actually complex machines with gearboxes that require automatic transmission fluids and filters, that need to be replaced periodically. This oil is waste, too, and because to make a 400 MW farm you need over 100 towers, this means you're replacing this oil almost continuously.

@freemo @2ck

Then the most important factor: wind and PV power have extremely low surface power density (how many watts from square meter), and they have very low capacity factor (percentage of operating at full power during a year).

In practical terms this means to replace one MW of fossil or nuclear power plant with wind or solar you need to occupy 50-200x larger area, and then 3-8x more for surplus capacity, and then double that in energy storage.

All that area eventually means waste.

@freemo @2ck

Life-time of PV panels and wind turbines is 20-30 years.

After which they become, well, "toxic waste" with high content of metals such as cadmium. They require careful decommissioning, recycling and waste management.

Failed PV farms did contaminate vast areas with heavy metals in the past.

@freemo @2ck

This is counter-intuitive but it's a fact, if you look at material balances. Modern PV and wind turbines are way more than "some wire". In addition to steel and concrete they require special alloys and rare earth metals. All of which are being mined in huge open-pit mines that produce mining waste. And because especially rare earth metals usually coexist with radium and uranium, the waste is usually slightly radioactive.

@freemo

Avoiding "hazardous waste" *and* "greenhouse gas emissions" looks quite contradictory 🤔 so I'm a bit concerned that this "caring ethically" is nothing more than a selling point targeted a specific customer sector.

@profoundlynerdy @wim_v12e @changaco

The power of capitalism lies in its flexibility and "whatever works" pragmatism. If you start artificially limiting what is allowed and what is not then it's not, then it loses this pragmatic approach at the cost of dogmatism. Smith specifically did not come up with his ideas for public schooling (as an example) from ideological position, but he built an evidence-based argument for it.

@profoundlynerdy

Thanks! To be honest, I last used Perl in 90's and never really followed its evolution. I code in Python and C mostly. Future of programming languages is driven by technology just as well as by mere human herd instincts , so hard to predict...
