Tl;dw:
Most tech is expensive when new. Prices usually come down as it ages into the market.
Are any of these points unsolvable engineering problems?
The main issue is that the approach is too naive. Organic tissue has blood vessels that bring nutrients and oxygen to the cells while removing waste. This is what allows tissue to grow in three dimensions. When you just have a bunch of cells in a vat, then cells in the middle of the mass have no way to get nutrients or dispose of waste. The other big problem is the lack of an immune system, so any contaminant can quickly grow in this substrate.
A better approach could be to try growing a more complex organic system that includes muscle tissue and maybe even organs such as heart and kidneys. I imagine this is a solvable problem, but it might not be the best approach.
A different approach I saw was to modify plants to produce meat like tissue. People have been playing around with this approach as seen here. That seems a lot more promising to me because growing plants is a lot easier than trying to culture cells in a vat.

Currently, yes.
@OsrsNeedsF2P @thevoiceofra That might work, depends on the details. Specifically how much of that 50$ is RnD they haven't written off as a loss yet.
If they can sell a DIY kit and the ingredients, we could do the same thing for lab meat that we do for IPAs and coffee roasting?
After watching the video, it sounds like that won't be happening. Too complex and specialized to do at home. Sounds like lots of filtration, chemistry problems.
I'll be sticking with the tofu and stuff I've been surviving on for the last 30+ years.
These lab meats are completely unecessary. Vegan replacements for meat using cheap, ordinary grocery-store ingredients, have come a long way in the past few years, mainly due to the wizard-like powers of vegan chefs for experimentation and reverse-engineering. Look up any "X replacement" recipe on youtube, try it, and you'll see how pointless "lab-grown meat" is.
I applaud the meat replacement companies for making it and you for eating it, but the fact of the matter is that most people aren't vegan or vegetarian. Around the world, meat consumption is rising. If products made from actual animals are to become a thing of the past, it will likely be through cultivated meat, dairy, etc.
If these products (or similar products) are just as good and can come at a more competitive price, there's no reason they won't become a standard, especially in developing areas where meat is simply too expensive
You don't have to be strictly vegan or vegetarian to eat these products. I eat meat, but I'd rather eat a little less, if I can replace it with foods with similar nutritional content
Cooked meat slurry is a delicacy where I live. It's called scrapple.
