A Response to an "Anti-Vaxxer".

"... the big question is whether the current vaccine is still appropriate given the new variants."

The prevailing variant in Singapore now is Delta. It is more transmissible. And has been shown to infect Children more. So, your belief that "Kids immune are tip-top, unlike our half-dead seniors" is a fallacy.
Also, MIS-C.
And "Long Covid."

"what's the rush?" No rush. take your time. If you do not need to work for a living, if you child do not need to go to school, if you are prepared or prefer to isolate at home, and avoid social situations, if you would like to be a "hikikomori" (and wish your family to be hikikomori too), your best bet to avoid the Delta or Omicron (if and when it becomes prevalent) variant is to withdraw from society? Or did you have another viable plan?

Omicron: Variant of Concern

 So there is a new variant (of Covid-19) now.

• The WHO on Friday named the variant Omicron, classifying it as a variant of concern
• Singapore announced restrictions for travellers who had recently been to seven African countries believed to be at risk from a new Covid-19 variant
• The variant is reported to have more than 30 mutations in the spike protein alone, of which four of them believed to be able to neutralise some treatment options
• More studies are need to determine whether the mutation can diminish the effectiveness of vaccines, or if it is more contagious
• Experts say if the variant spreads widely around the world, it will eventually arrive in Singapore

So, should we be worried?

How Social Media (Facebook, Google, Youtube) is not good.

"The main culprit, Haugen said, is Facebook’s desire to maximize engagement, which has turned its algorithm and platform design into a giant bullhorn for hate speech and misinformation... For clickbait farms, getting into the monetization programs is the first step, but how much they cash in depends on how far Facebook’s content-recommendation systems boost their articles. They would not thrive, nor would they plagiarize such damaging content, if their shady tactics didn’t do so well on the platform."

From "How Facebook and  Google

fund Global Misinformation."

Protecting "Gig Economy" workers

We should not treat gig economy workers as employees. (Unless they want to and their "employers" are willing to - mutual consent.) 

The current set-up provides a lot of flexibility for the workers as well the platforms (ersatz "employer") that offers the gigs. And changing that would affect that flexibility and advantage of that business model. (Which may well destroy that business model and business.)

BUT (and this is a VERY IMPORTANT BUT), these workers MUST HAVE BASIC PROTECTION!

Certainly, they need more protection than what they currently get. So there should be mandatory, basic protection for these gig economy workers.

But why? Why can't they just work in a regular job?

This assumes that regular jobs are a) still available in the future, and b) what the new economy workers want. And c) what new business models want or need.

So let's take it as a given that in the future there may be many "gig economy" jobs, and that some people may prefer "gig economy" jobs for the freedom or the fit with their life or needs.
