If you don't work directly on products that have real customers lined up and a prospect of actually making money within 2-3 years, you are going to be non-essential when the the 2019 extinction level layoffs begin. 1/2 of R&D can be cut based on that standard alone. Prepare now. You better have an emergency savings account storing at least 9 months of take home pay our your just plan dumb.
I agree with the person that posted this (@VMNAcKz-3wcn ). A lot of people are right to feel unsafe about their jobs if they are not directly contributing to making profits.
