If there was great potential, then there would be more investment. The people investing do it as their job. They do know what they are doing.
No, sorry. It's not that simple. Without giving too much away (in reference to my other posts) I am a development scientist for a medical company. I can't tell you how many projects with absolutely astronomical market value do not get fully started because
"this is a new area, so... rather than invest £50M of our own money in research costs to show proof of principal, why don't we wait until someone else figures out the basics and then build our own treatment off of that research. That means we don't risk our 50M upfront." Investors do not look at people's suffering, they do not look at "what could this be worth in 10 years" - they look at "what's a proven, safe, semi-decent return for my clients' money."
And 'treating cancer' isn't a thing in of itself. There are approximately 200 types of cancer. Most of which will require independent, specific and/or specialised treatment pathways. It's not a case of
"this tablet cures testicular cancer, so it'll cure brain cancer too." Money given to cancer research labs isn't taking money away from hearing loss research labs. It's that hearing loss research labs are not getting the funding at all.
With how every single hearing regeneration company has already failed, it's not the most attractive investment.
Compared to diseases like cancer, the funding being given to hearing loss research is so tiny it's not even on the map (believe me... I know). Without the huge funding cancer has received, the treatment would be far worse than what's available today. With how many hundreds of billions (possible more?) have been invested in cancer globally, you'd think we'd have a cure, no? No, cancer treatment has remained unchanged for some time now. Does that means it's a dead end and an unattractive investment since there's no cure-all-cancer-pill yet? Of course not.
The hearing aid market alone is only $7.5b. There are probably less people with tinnitus than with hearing aids. Or less people with severe tinnitus anyway.
Non relevant comparison. In the UK alone, 6 million+ people require hearing aids, yet only 2 million are prescribed them through choice. Either social issues (I don't want a hearing aid) or denial. 1 in 6 UK adults have hearing loss. 1 in 10 have a degree of tinnitus. Many people are told their hearing is bad, but not bad enough to benefit from a hearing aid, so aren't even given the option.
If somebody told you
"you can have these hearing aids for the rest of your life", most people would say no thank you.
If somebody told you
"we'll schedule an appointment, a small injection in your ear and within a few months you'll have regained x% of your hearing", most people would say sign me up.
I see where you're coming from, but in the next decade or so, hearing loss occurrence is going to reach critical mass; how many kids these days do you see with headphones permanently in? But it seems only a few companies are forward thinking or willing to take the risk in development the cornerstone technology that will cure hearing loss. And I hope when successful, their researchers and investors reap the rewards.
