Who demonstrated a vision of an easy to use computer in 1968?

The correct choice is Doug Engelbart, who is renowned for his pioneering work in the field of human-computer interaction. In 1968, Engelbart demonstrated a vision of an easy-to-use computer through what is now famously known as "The Mother of All Demos." During this demonstration, he showcased several groundbreaking technologies, including the computer mouse, hypertext, video conferencing, and collaborative software. Engelbart's vision emphasized the potential of computers to enhance human capabilities and improve communication and collaboration, laying the foundation for modern computing and user interfaces.

His work not only foresaw the user-friendly personal computers we use today but also contributed significantly to the development of the internet and interactive computing. Engelbart aimed at augmenting human intelligence through the use of machines, which aligns perfectly with the concept of an easy-to-use computer.

In contrast, others listed in the choices played significant roles in the computer industry as well, but their contributions are associated with different aspects and later developments in computing technology. Bill Gates is known for creating Microsoft and popularizing personal computing; Steve Jobs is recognized for innovations in product design and technology with Apple; and Robert Taylor was instrumental in networking and connecting computers but did not specifically present a vision for user-friendly computing in the same context as
