Somewhere in your schema I hope there's a placer for an effective treatment!
That would go a long way to mitigating the misery. Admittedly, people being how they are, there would likely be a lapse in caution if survival and a comparatively short recovery were all but guaranteed.

Hmm. Not sure about that: Covid is caused by a coronavirus, and the common cold is caused by one of four viri: human rhinoviruses, parainfluenza viruses, adenoviruses, and ... coronaviruses.
If your theory held, then given how long we've lived with colds, everybody should be immune by now ...

They're finding people who are. Well, they're checking blood samples in storage for a decade or so...and finding the antibodies needed to ignore this version of corona...so the assumption is other people are already immune.
The "cold" viruses are mutable. That's why you can catch a cold over and over again, despite having had one already. So, even if they come up with a vaccine for *this* version, it will be useless three and a half days later when the virus says 'elephant you' and changes again.
EDIT: To clarify - the old blood they tested has the same antibodies that are tested for currently for Covid19, not that it indicates Covid19 was around a decade ago. So, either the current antibody tests are useless, or corona is corona is corona is corona, to mangle Gertrude Stein's poem.

Actually, the flu in particular and the that family of virus' have the ability to easily jump between humans and swine.
That's why, in days gone by, we typically had things called "the Asian Flu", the "Hong Kong Flu", and similar names. Although the practice is done world wide, it was particularly common in Asian countries for people to raise swine in their "front yard (at least the rural population) as a suppliant to their diet. It was an ideal setup for the jump, back and forth, and the appropriate mutations.
That's why they'll call something H1N1 as a type of flu: the "core" is the same as before (a nasty one) whilst the out jacket has mutated enough for our immune systems to no longer recognize it.

What's the POV here about post COVID for Entertainment, Food or Hotel segment? How long do you think it will take for these industries to be back to where they were pre-COVID?

Many won't. They won't be able to make enough money under the restrictions to recoup what they lost in the last N months. And - of course - insurance companies will find a way to ensure that they weren't quite as covered as they thought they were ...

Here in the UK many have already collapsed. Some businesses are still closed while others are opening but restricting numbers. As to how long before they are back to normal, your guess is as good as anyone's.

I'm not sure the pre-COVID situation was that good... Not in the hotels at least...

I don't see the prices coming down now that foreign tourists are barred from entering the country, either.
The hoteliers claim that the problem is that between the high taxes charged in Israel and the hotel's fixed costs, they have little room to lower prices. Personally, I have my doubts. Until the COVID epidemic, large groups could get very big discounts, and I doubt that they were losing money on them.

Unless we have some Israeli hoteliers among the members, I thought this was a not-too-controversial, non-political topic.

My wife is retiring in a couple of weeks after 27 years with a casual dining chain in the US. This is a direct result of Covid. Anyone (in upper or middle management) near retirement age was offered a really good package. She was only 2 years from her planned retirement and the deal was too good to pass up...besides, if she had stayed, it would have meant more responsibilities (restaurants) for less pay.
As to the question at hand, this pandemic has already caused many dining establishments and bars to close, at least for now...the ones with deep pockets may survive but not without massive layoffs. In the meantime, fast food and delivery are thriving.
As the numbers of cases continue to rise in many parts of the country, including my area there is a new problem arising...people are scared to come to work as some staff have become infected. Now is not a good time to be in the restaurant business.
I don't see things getting back to normal until a vaccine is widely available...maybe by 2021 but at this point, nobody knows.

I have a parser generator called Parsley[^] which I have not updated in a while.
One of the neat things it can do is link several grammars** into several different parsers, and then link the different parsers it generates together so they can use each other to perform sub-parses. There are a number of advantages to this, including the fact that you can disambiguate grammar constructs by factoring them out over multiple grammars - since the parsers each have their own parse table, you won't have duplicate entries which causing ambiguity.
But I just realized I could parallelize the code generation for it too wherein each different grammar crunching task runs its own CPU bound operation to create the parse tables. And it's easy.
** a grammar is a document that tells the parser how to parse something. Usually it's written in a variant of BNF or EBNF.
I came up with all of this during a conversation about schizoaffective disorder. My mind is really funny sometimes.
I think it helped that I've been doing so much async stuff lately.

Interesting
Can you elaborate a little on how to decide when to activate one (or more) of
the (sub?) parsers?
Of course you can activate a number of parsers simaultaneuously on a given input (sub)string
Long, long time ago in one of the compilers we used a mix of bottom up and top down (recursive descent) parsers, is that (more or less) similar to what you are describing?

The share a symbol table, so when you reference a symbol from a foreign grammar it invokes the subparser
like here's an excerpt of a grammar i wrote:
/ SlangStatement.xbnf
// This is the XBNF spec for Slang Statements (gplex version - unicode enabled)
// Slang is a CodeDOM compliant subset of C#
@import "SlangExpression.xbnf";
// Statements
// we use this with our skipped lists to get comments on to relevant nodes
Comments<abstract>; // { lineComment | blockComment }
Directives<abstract>; // { directive }
VariableDeclarationStatement= varType Identifier "=" Expression ";" | Type Identifier [ "=" Expression ] ";";
Here I bolded the import line which will cause this parser to reference the SlangExpression parser generated by SlangExpression.xbnf (a grammar like this one)
I also bolded all the foreign symbols. These invoke a subparse when encountered
Member 12982558 wrote: Of course you can activate a number of parsers simaultaneuously on a given input (sub)string
I think maybe I wasn't clear about where the parallelization opportunity is. It's in the generation of the parser source code from the grammars. That's what I can make parallel. It means faster dev cycles for the parser because it doesn't take as long to generate. ETA: but i could parallelize the backtracking. Not sure if I would gain or lose perf doing that though

It sounds like it. Here's I'm assuming your parsers call other parsers like the top-down delegates to the bottom-up for some things. If so, this is like that except it's all top down, not several different algorithms.

What's the local consensus on Blazor WebAssembly technology?
Is it worth learning? Do you think it will become important?
Blazor | Build client web apps with C# | .NET[^]
The difficult we do right away...
...the impossible takes slightly longer.

Coming from someone who got out of web development years ago, I haven't used it yet, but I've read quite a bit about webassembly, and my feeling is just from the buzz around the related tech like blazor is it's gaining momentum. I think it will entrench itself in the web as it gets more sophisticated.
If you want to be prepared, I'd say learn it. Otherwise focus on current web technology with an eye toward maybe learning it down the road.
That's my $0.02 not having programmed with it. Offered FWIW

It's cool but what about performance? Particularly when I tried it last, the time it took to download the WebAssembly pieces into the browser was, well, unacceptable. I do not tolerate "loading page" spinny's very well.
It's awesome to write C# instead of Javascript, but how well does it integrate with third party libraries? They make claims, I'd like to see real use-case examples.
Client/server code re-use is a great idea, but last time I checked, Blazor didn't support an implementation of the latest C# language. This might have changed?
I actually loathe ASP.NET, particularly the mixing of HTML and code, server-side "compiling" of HTML pages (ie Razor), etc.
When it comes to web development, I prefer lean, mean, and performant. If that means I have to code in (preferably) TypeScript, great. It also means I am very very careful about what bloatware frameworks and libraries I add to my web applications. At the moment, Blazor is cool tech but I would never use it for a production environment. That's not Blazor's fault, I have the same attitude toward many server-side and client-side frameworks/libraries.
