This website paints Intel with dark colors, because it is mostly attended by those who were kicked out earlier this year. Some of those feel huge disappointment. The last layoffs episode has been percieved as an ugly action. But they got nice seperation packages. Much higher than other companies provide. I personally met a bunch of layed-off friends that percieved their own layoff as fair and respectable.
Other companies layoff as well from time to time. There is no job security in any corporate.
Regarding the future of Intel. You can never know. It looks grey these days. But Intel overcame some crisises in the past decades (PowerPC, Alpha, Opteron, Athlon, Sparc, Transmeta. Where are all these threatening competitors these days?)
I stay because I like my day job. I like the challenges, my team, the supportive atmosphere and I'm able to develope my skills at Intel.
Take everything in proportions.
I'm an happy SW Engineer at Intel for many years.
