We've spent a lot on nuclear and it's still too expensive for all but the largest countries to afford. We've spent a lot on wind and solar and every country can afford them.
Tried it. Didn't feel the natural conversation that ChatGPT has, felt more like a regular old 'how can I help you' chatbot. Asked a few questions, picked out some keywords and pasted a very generic bit of advice that wasn't really conversational and didn't seem to take into account information already provided.
Just a one note text page. I have a normal list, and linked a set of sub lists that link from the top. Then I have a 'today' list of the really important stuff that must get done that day.
That's great if we all live in control rooms. The part 'calories in calories out' misses is that what you eat, how you eat, where you eat, how your body reacts to what you eat, who you eat with, where you live, what food is available, the price of food....all impacts how much you eat.
A very basic but effective home gym: A barbell and 140kg of bumper plates, Squat/bench stands, bench, slam ball, dumbbells and a small range of kettlebells. The whole thing cost about the equivalent of a year's gym membership but have lasted two years so far and show no sign of wear.
Being able to lift something heavy on a regular basis over the last year has been a massive boost for my mental and physical health. You don't need expensive gear, some of my best workouts are from a metal bar wedged over a loft hatch, you just need to have something and use it.
Home charging is great, but it only works out for people who have off street parking. That leaves a lot of people without off street parking that must use public chargers only, and that's very inconvenient.
Keychron K2. It's the closest to a 'do everything well' keyboard I could get. It's wireless at home, but wired at work (usb C too). It's mechancial and feels good. It's got a switch for mac & pc layouts. It's got a good utility illumination without looking too gamer. Only thing I don't like about it is it's a bit thick/high, means you have to use a rest with it.
There's two kinds. The certs do need paying for and test centres. Trailheads are free and give you badges. These are great as an intro, but I think many employers want the real certs.
If a business wants to hold cash outside of a bank, it has to use bank notes. This would give them the option of holding digital currency directly.
Also you'd expect a ground up design of a digital first currency to include much lower cost of transfers enabling micro transactions and much better speed to settle.
Bikes aren't great for the 'last mile' where you might get off a train and have a bit further to go. You can ride a scoot in pedestrianised areas too normaly, and you can't on a bike. Far harder to stash a bike behind your desk at the office, much easier with a scoot.
Of course the downside of this convenience is stealability.
