Lobster is a bug; it used to be 'ick' and now its 'yum'. The ick factor is cultural. No reason the OP can't be right - if bugs are tasty, and some people start eating them, and then more people, they could easily become a regular thing.
Mind you he finds the texture of boiled eggs repulsive too, so it might just be him.
Lobsters aren't molluscs, they're crustaceans.
Not even the same phylum.
Just like cod, which my Hull fishing-town relatives taught me is a dirty, wormy fish unsuitable for consumption. All you can do with it is sell it to the naive land-lubbers...
That said we are going to look at a timeline of decades rather than tomorrow. I mean Tofu has been around for how long? And it is still somewhat of the beaten path.
Okay, so it's a coconut crab, not a lobster, but...
You eat farmed insects which are clean and you can be sure they're free of pesticides or other agrichemicals.
Farming insects uses less land and water than farming meat and is less problematic regarding cruelty.
If there is a market for bugs something will end selling ilegally wild bugs (cheaper, better profit margins). This is what history tells us again and again.
I really hope that we as species can be more smarter in the future about this. Famines are not caused by people not eating bugs, are caused by people creating wars by design, etc...

Canine / felines are carnivores (omnivores these days, but you get the gist) and their muscle structure / diets cause them to taste 'off' and be tough fleshwise. Not to mention that they're worth more as biological weapons / companions.
There are also more scientific reasons, for example:
There was a quick deterioration in the men's physical condition during this journey. Both men suffered dizziness; nausea; abdominal pain; irrationality; mucosal fissuring; skin, hair, and nail loss; and the yellowing of eyes and skin. Later Mawson noticed a dramatic change in his travelling companion. Mertz seemed to lose the will to move and wished only to remain in his sleeping bag. He began to deteriorate rapidly with diarrhoea and madness. On one occasion Mertz refused to believe he was suffering from frostbite and bit off the tip of his own little finger. This was soon followed by violent raging—Mawson had to sit on his companion's chest and hold down his arms to prevent him from damaging their tent. Mertz suffered further seizures before falling into a coma and dying on 8 January 1913.[8]
It was unknown at the time that Husky liver contains extremely high levels of vitamin A. It was also not known that such levels of vitamin A could cause liver damage to humans.[9] With six dogs between them (with a liver on average weighing 1 kg), it is thought that the pair ingested enough liver to bring on a condition known as Hypervitaminosis A. However, Mertz may have suffered more because he found the tough muscle tissue difficult to eat and therefore ate more of the liver than Mawson

It is highly likely that if those explorers had asked the original breeders of said animals, they'd have been told strongly that eating them was a bad idea.

Clark never ate dog, couldn't bring himself to break the cultural taboo.
In the dry areas of what is now eastern Washington, in fact, where there was little if any game and the only other choice was dried salmon, usually impregnated with sand, the men came to prefer dog.

Deciding something is delicious or not has more to do with culture and upbringing than actual taste.
Cats are said to taste pretty much like rabbit. Edible, but nothing really special.

So everyone can taste bitter, but not always from the same things.
A similar thing is probably at work in people who find raw tomatoes extremely unpleasant.
