Re: uk.gov don't need an excuse ...
What are satellites needed for these days? Comms? No, the worlds covered by fiber. Sat TV? Nope broadband again. weather forcasting? Maybe... is that a big market? Military, spying on Asia and wishing you weren't a nation of micromanagers perhaps?
Solar is where it's at! Payback for my farm is ~5 years, if I add 28kWh of lithium (overkill) and do an off grid its ~8 years. Free money with a rapid payback, just as long as I hire the sparkies and welders myself, rather than pay a 'specialist' solar company that triples the price. China and Korean dominate that.
Electric vehicles are next.
Superconductors in pure research, are next.
Lots of things might be the next big thing.
Nobody can set up a business in UK the way they do in Asia. Here, you simply decide to do something and do it and the office space is cheap, and the staff are cheap and the regulation is "post-liabiity", not "pre-permission of a numpty on a power-trip".
If I was Boris, I would make the first £100k of money a person makes in their life as self employed, tax free. You set up a business, try to make it successful, you lower all barriers to zero, free co-working spaces, tax man helps you with the accountancy, you have webhelp, specialist marketing help available dirt cheap, and you have a window of your first £100k of sales and that's it, one shot in life to make your new thing. See what new things your people can make if you give them the chance.
You don't know what's next till it happens, all you can do is create the space for there to be a next. You won't compete against Asia, but you can compete *with* Asia.
So Boris, bless him, imagined a money island like Singapore. Yet has taken no steps to achieve that. Singapore is a faded glory, it was a port hub for a while, repacking Chinese cargo ships by destination, but China does that now. It was a money hub, a stock investing hub, now its OECD'd and customers do the numpty dance, money went to HongKong instead, now its a garden with lights show, a theme park island, an overpriced tourist destination.
He needs a different role model for the UK. I don't think he has it.
