the same experts that tried to scare us over Y2 K that was blown all out of proportion only affected a few old machines,
Debunked many times by those of us who actually worked on Y2K. If you think it wouldn't have happened, or only a few dates would have been affected cast your mind back a few weeks to the debacle of Lloyds and TSB trying to separate their systems - thousands locked out of their accounts, given access to other peoples accounts and such like. Oh yes, not a problem if you don't bank with them, but absolute shit if you did.
Greenland didn’t suffer,
Because Greenland with a population of 50,000 and one major industry fishing, spent 3 years negotiating with what was then a much smaller union, of either nine or ten members.And are still part of the Kingdom of Denmark, which is still an EU member. No comparison with a UK of 65 million and preparation being babbling 'Brexit means Brexit' and 'A red, white and blue brexit'. Maybe they had idiots who babbled Greenland exit is Greenland exit, but at least they got on with the job.
yes there will be some adjustments to begin with,
Oh yes, the NHS will be so flush with cash, they won't know how to spend it.
none of you know 100% what will happen
That goes for life generally. None of us know we will be alive tomorrow, but it doesn't mean that we don't make plans, don't buy food, don't pay the mortgage etc..
