I wanna found a company after finishing education and working for a few years.
In your opinion: Is it still worth to go into the app market or shall I advance and aquire knowledge in the vr market in the meantime?

VR seems to be the "appmarket" of the 2020's.

Playstore is already very saturated til now.

Tbh I don't think VR s gonna survive upcoming years.
People aren't going to use VR much as hyped cz its always an extra accessory. The trend is in the other way, remove shit and get things done!
Just look around! You'll get it. From virtual assistant which made no UI is the new UI to Machine learning which made no conditions is the new way to code.!
Its always good to get into the flow current when its necessary, getting too early or too late to something before analyzing the market is a bad idea.

Just my thought.

Don't totally agree with that.
But I agree vr will not be spread as broad as other tech, it will be more niche.

I think VR is going to be big but I don't think it will replace anything we know or use now.
The reason being that it takes effort to go into VR. So it is only acceptable for sessions as opposed to a quick look on a phone.

There is always going to be demand for Apps. So wouldn't abandon it completely.

I think I will finish one more app within the next month and then start with unity. :)
