Ann: 2022 Half Year Results & FY2022 Outlook, page-159

Synthetic data is not going to make any type of commercial impact in the forseeable future due to its accuracy. It will play a role in the basic recognition based on dimensional inputs but still very inaccurate and basically useless doesn't mean it won't improve in future.
Appen is not going to lose on the ad spend market - but depending on Big Tech the company is at the mercy of the ad spend business cycle. All Ad spend businsses in the US have had massive declines and Appen is leveraged to them.
The way forward is not in advertising - it's machine learning applications for enterprise.

The amount of nonsense and mis information is astounding. Machine learning in enterprise is starting to scale and data to these enterprises is very small. But expected to grow from $5b in value to $10b in value by 2024. Same diarrheoa was posted on LYC but for different reasons. The industry just needs to grow and mature a little more and if all things are equal it will reflect in its finances.
APX has an extremely string balance sheet and whethered the transition well and likely at the tail end of it. We should see some improvement by FY 23 and scale to enterprise to become a reality by FY24.
Appen is the outright leader in this niche market and demand is definitely there in a market that has yet to mature.
